1. Adel Barakat, Kuniaki Yoshitomi, Ramesh K. Pokhare, Design Approach for Efficient Wireless Power Transfer Systems During Lateral Misalignment, IEEE Transactions on Microwave Theory and Techniques , 10.1109/TMTT.2018.2852661, 66, 9, 4170-4177, 2018.09, This paper methodizes efficiency improvement during lateral misalignment for the wireless power transfer (WPT) system using two coupled semielliptic defected ground structure (DGS) resonators. We design the WPT system using a scaled value of the available mutual coupling between the resonators at perfect alignment. This scaled mutual coupling value enforces over-coupling regime, and the WPT efficiency is lower than the peak one. Then, during lateral misalignment, WPT efficiency improves until it peaks at critical coupling. Next, with further misalignment, the efficiency drops as the system enters loose coupling regime. The proposed method consists of two steps. First, we derive an analytical approach to determine the scaled mutual coupling value for efficiency design during lateral misalignment, and second, we improve the maximum obtainable efficiency by careful designing of the DGS structures’ profile. We verify the proposed method by implementing the WPT system at 300 MHz, which shows a peak efficiency of 80% for a size Do× Do = 40×40 mm2 with a transfer distance d = Do. During misalignment, the efficiency is higher than 50% for a lateral shift up to ±0.75 Do..
2. Hany A. Atallah, Adel B. Abdel-Rahman, Yoshitomi Kuniaki, Ramesh Kumar Pokharel, Design of compact frequency agile filter-antenna using reconfigurable ring resonator bandpass filter for future cognitive radios, International Journal of Microwave and Wireless Technologies, DOI: 10.1017/S1759078717001556, 10, 4, 487-496, 2018.05, In this paper, a new miniaturized frequency agile filter-antenna with a wide reconfigurable frequency band is proposed for interweave cognitive radios (CRs). A tunable bandpass filter (BPF) composed of a symmetrical ring resonator is cascaded to the feed line of an ultra-wideband planar antenna. The structure of the proposed ring resonator BPF is simple and compact so that the total size of the proposed filter-antenna is smaller than that of a conventional system made of a separate antenna and BPF. The reconfigurability of the proposed filter-antenna is achieved by changing the operating frequency of the BPF by loading the ring resonator with a single varactor diode at its center. The fabricated prototype has successfully achieved a wide operational bandwidth of 1.43 GHz which covers continuous narrow bands from 4.65 to 6.08 GHz. Moreover, the operating tunable narrow bands have stable radiation characteristics. Good agreement bet een measurement and simulation results is demonstrated..

Abdel-Rahman, Yoshitomi Kuniaki, Ramesh Kumar Pokharel, CPW-Fed UWB antenna with sharp and high rejection multiple notched bands using stub loaded meander line resonator, International Journal of Electronics and Communications (AEU), 83, 22-31, 2018.01, This paper presents a CPW-fed UWB filter-antenna with sharp and high rejection multiple band notches for band-notched UWB communication applications. The band notch operation is achieved by employing a sharp bandstop filter (BSF) with multiple reject bands using only one element meander line resonator at the bottom layer through theoretical calculations and parametric studies. The adjustment of the notched bands is successfully accomplished by loading the meander line with open ended stubs to modify the harmonic frequencies to the desired bands. The structure of the proposed BSF is simple and compact so that the proposed filter-antenna is achieved with the same size of the reference UWB antenna without an extra area. Measurement results show that the proposed filter-antenna has two notches at the WiMAX systems operating in the 5.8 GHz (5.725?5.85 GHz) and at the international telecommunication union (ITU) operating in the 8.2 GHz (8.025?8.4 GHz). Also, it has sharp rejection characteristics at the edges of the federal communication commission (FCC) band for UWB communications. The experimental measurements are in good agreement with theoretical and simulation results for the BSF and the filterantenna. Moreover, the filter-antenna exhibits stable omnidirectional radiation patterns except at the notched bands..
4. Fairus Tahar, Adel Barakat, Redzuan Saad, Kuniaki Yoshitomi, Ramesh K. Pokharel, Dual-Band Defected Ground Structures Wireless Power Transfer System With Independent External and Inter-Resonator Coupling, IEEE Transactions on Circuits and Systems II: Express Briefs, DOI: 10.1109/TCSII.2017.2740401, 64, 12, 1372-1376, 2017.08, This brief proposes a design methodology based on the admittance (J-) inverters for a dual-band wireless power transfer (WPT) system that employs two cascaded circulars defected ground structure (DGS) resonators with different capacitive loading to guarantee distinct resonances. A single microstrip line excites the two DGSs, and when two DGS resonators are coupled back to back, it transforms to a dual band pass filter leading to WPT at both bands. Each of the DGS resonators has independent coupling. Thus, the realized J-Inverters are designed independently. Also, we employ a single stub for the matching. This stub appears with a different length according to the operating frequency; hence, an independent external coupling is achieved at both frequencies. A compact size of 30 mm × 15 mm is fabricated achieving a WPT efficiency of more than 71% at a power transfer distance of 16 mm for both bands (0.3 and 0.7 GHz)..

Antenna element is composed of monopole antenna with truncated ground plane. Both antenna layer and ground pattern are placed on the top of the substrate. It is suitable for the miniaturized wireless devices such as three dimensional integrations or stacking of the multi layer. To obtain the wide band and flat gain characteristic, rectangular notches are inserted on the antenna layer, and optimized the current flow and antenna impedance. For array antenna, by changing the length of the CPW feed line, the antenna gain is suitable in the wide band which is 7–10.4 GHz (23 dB bandwidth). The total antenna size of the two array antenna is 16 mm 3 11.5 mm 30.418 mm. Simulated gain is 3.8 dB..

The proposed antenna utilizes two symmetrical short circuited quarter wavelength resonators at the top layer and close to the ground to create a single notch. The switching reconfiguration is achieved by changing the length of resonators to prevent the interference to the primary users that are operating in the wireless local area network (WLAN) band at 5.725–5.825 GHz and the international telecommunication union (ITU) band at 8.05–8.4GHz. The center frequency of the notched band can be tuned by selecting the length of the resonators, which is achieved by employing two ideal switches. Moreover, the proposed antenna has been fabricated and tested. The experimental data confirmed that the proposed design can selectively have a band notch over the two existent desired bands..

Abdel-Rahman, Yoshitomi Kuniaki, Ramesh Kumar Pokharel, Mutual Coupling Reduction in MIMO Patch Antenna Array Using Complementary Split Ring Resonators Defected Ground Structure, Applied Computational Electromagnetics Society Journal, 31, 7, 737-743, 2016.07, In this paper, complementary split ring resonators (CSRRs) defected ground structure (DGS) is introduced to suppress surface waves and to reduce the mutual coupling between E-plane coupled two elements of a microstrip patch MIMO antenna array. The CSRRs-DGS is easily etched on the ground plane between the array elements. The CSRRs-based DGS acts as a bandstop filter between the array elements and operates in the same desired frequency band of the array at 9.2 GHz. Significant reduction of the electromagnetic (EM) mutual coupling is achieved between array elements with a reduced edge-to-edge spacing of 7.5 mm (0.22 ?o). Experimental results show that more than 30 dB isolation between the array elements is obtained using an array of CSRR-based DGS. Moreover, the antenna array parameters are successfully optimized with a numerical experimentation technique using a 3D full-wave EM simulator. The design of the proposed array is fabricated and measured for verification purposes. The proposed design has been simulated and validated experimentally. Good agreement is found between the simulated and the measured data..

Chai Eu Guan, Yoshitomi Kuniaki, Haruichi Kanaya, Derivation of the Optimum Distance between Periodically Spaced Vias for Leakage Suppression at S-band, MICROWAVE AND OPTICAL TECHNOLOGY LETTERS, 10.1002/mop.29776, 58, 5, 1257-1260, 2016.05, In this letter, the optimum center-to-center separation between vias in the conductor-backed coplanar waveguide (CBCPW) is presented for leakage suppression in the dielectric region. Leakage mechanism at high frequencies associated with surface wave or parallelplate mode were widely studied in the past. In this work, antenna arrays have been used to compare leakage in CPW and CBCPW feed network at S-band. By using identical antenna elements, CPW-fed slot dipole antenna array has been compared against CBCPW-fed slot dipole antenna array with a ground via fence. Instead of using shorting pins with minimum nonzero gap, optimum center-to-center separation distance between vias has been derived from the bandgap phenomenon. Approximately 20% of total loss across the frequency range of interest in CPW feed network obtained from the comparison of the CPW-fed antenna array against the CBCPW-fed antenna array can be attributed to unwanted leakage in the dielectric substrate..

The antenna consists of microstrip line-fed half slot, and an open-circuited stub is connected to the microstrip feed line to adjust the matching at the operated frequency band. A half slot is used for miniaturization, as well as due to concentrating the field at only half slot; consequently, it decreases the resonance frequency and improves the antenna radiation characteristics. The antenna radiates at 24 GHz with measured fractional impedance bandwidth of 9%. The antenna gain at the resonant frequency is 5.2 dBi. The proposed antenna shows about 60% length reduction. Therefore, the proposed half slot antenna could be used for energy harvesting applications, at 24 GHz ISM band, due to its compact size with improved gain value. The proposed antenna was designed using ANSYS high-frequency structure simulator (HFSS). The simulated and measured results show good agreement..

For realized circularly polarized wave, we use planar slot antenna. By optimizing the lengths and widths of antenna slot, resonances can be obtained at 5.8 GHz frequency. The antenna generates a circularly polarized wave providing a slot in the two orthogonal directions. Improving the gain by providing a slot in the same direction, arrayed structure is adopted. The final antenna size is 17 mm x 15 mm x 1.6 mm. Our antenna was fabricated on the FR4 substrate and impedance bandwidth is 310 MHz from 5.62 to 5.93 GHz. Moreover circularly polarized wave can be obtained..

― 太宰府市立東小学校の事例  ―, 日本臨床環境医学会, 2013.06, 目的】小学校100m内に建設された携帯基地局の電磁波が子どもたちの健康に及ぼす影響について、教室内の電磁波の実測および児童に対する健康調査結果を総合した解析する。【調査対象校および健康調査法】①対象校:福岡県太宰府市立東小学校(教室から約100m地点に携帯基地局設置)②調査方法:a)電力密度測定:校舎1階、2階、3階、玄関前、民家2階で測定。ETS-LINDGREN社製アンテナModel 3115とHEWLETT-PACKARD社製スペクトルアナライザHP 8592Aを使用。③健康調査票:児童の頭痛など症状17項目(いいえ、ときどき、いつもの3段階評価)、④自宅の家庭環境:家庭と携帯基地局からの距離(5段階)、児童の携帯電話使用頻度・無線ゲームの使用頻度(いいえ、ときどき、いつもの3段階)、⑤調査票の配布・回収方法:育成会総会終了後1~6年生児童150名(全児童数300名中)の保護者に調査票を配布しその場で回収。⑥統計解析:SPSSを用いた多変量解析(ロジスティック回帰分析など)を行い解析した。
【結果および考察】
① 健康調査票回収率:92%(138/150)、有効回答数:127名、有効回答率84.6% (127/150)
② 電磁波の測定結果:1階、2階、3階の順に電力密度が増大(表1)。携帯基地局のアンテナから見た俯角の差と障害物(1階)によって電力密度に差が生じていると考えられる。
③ 電力密度と児童の健康との関係:“体がだるい”、“いらいら”、“口内炎”などの有訴率は、電力密度が最も高い3階の4・5年生児童が最も高く、電力密度の最も低い1階に移動した6年生児童では低かった。一方、“耳鳴”や“頭痛”などの有症率は6年生の発生率が高い傾向が見られた。
以上のように、本調査では、教室内の電磁波と児童の症状有訴率との間に相関関係が認められた。また、児童の有症率は、教室内の電磁波ばかりでなく、児童の家庭内環境、携帯電話使用頻度・無線ゲームの使用頻度との間にも相関が認められた。
これらの結果から小学校近傍の携帯基地局からの電磁波が児童の健康に何らかの影響を及ぼしている可能性が示唆された。携帯基地局からの電磁波が児童の健康に及ぼす影響を評価するためには、今後、教育員会の協力の下、専門家による教室内電磁波の継続測定および追跡健康調査が必要だと考える。

43. 吉富 邦明, 近藤 加代子, 新城哲治, 小学校における携帯基地局からの電磁波の実測と低減対策, 日本臨床環境医学会, 2013.06, 【目的】 小学校の校舎の窓ガラスに貼った電磁シールドフィルムによって隣接する携帯基地局からの電磁波の遮蔽対策を実施したので、その効果について電力密度の測定結果を報告する。
【対象と方法】 太宰府東小学校では、敷地から約40m、教室のある校舎から約100mの位置に携帯基地局が設置されている。携帯基地局は校舎の北側にあり、教室の北側には廊下がある。廊下の一部の窓ガラスは金属網入りで電磁遮蔽が期待できるが、大半の窓ガラスは普通ガラスである。そこで、携帯基地局に面する廊下の窓ガラスに電磁シールドフィルム(YSHIELD社RDF50)を貼り、電磁遮蔽効果を平成25年4月に測定した。測定にはスペクトルアナライザ(HP8592A)とアンテナ(ETS-LINDGREN Model 3115)を使用し、マックスホールド機能を用いて観測時間中の最大電力密度を求めた[1]。電力密度は6分間の平均値で評価されることが多いが、時間とともに変動し、最大電力が平均電力の10倍になることも珍しいことではないことが知られている[2]。
【結果と考察】 窓を開けた時と閉めた時の電力密度はそれぞれ1.08μW/cm2と0.11μW/cm2である。また、廊下の窓とシールド対策をした教室の窓を互い違いに開けるなどして、教室内から携帯基地局が直接には見通せないように窓を開けた時の電力密度は0.15μW/cm2であった。フィルムを貼る前の平成24年3月の測定では、窓を開けた時と閉めた時で電力密度はそれぞれ2.12μW/cm2と1.28μW/cm2であった(当時の運用周波数帯は875-880MHzおよび2135-2150MHz)。この測定結果から、フィルムにより窓の開閉にかかわらず電磁波が遮蔽されることが分かる。
【結論】 電磁シールドフィルムを窓ガラスに貼ることにより、電力密度を欧州評議会による長期被曝レベルの予防的しきい値である0.1μW/cm2のレベルにまで低減できることが確認できた。
