  • Gain Enhancement of Optical Leaky wave Antenna Excited by Parabolic reflector with Photonic crystal

    Sugaya Satoshi, Iida Wataru, Arai Hiroyuki

    IEICE Communications Express   10 ( 9 )   629 - 633   2021.9  [Reviewed]

    DOI CiNii

    Language:English   Publishing type:Research paper (scientific journal)   Publisher:一般社団法人 電子情報通信学会   Joint Work  

    <p>This paper presents gain enhancement of leaky wave antenna by parabolic reflector of photonic crystal. A leaky wave antenna has been proposed as an antenna for optical wireless communication. This antenna is excited by a parabolic reflector made of photonic crystals. This excitation method is very compact, resulting in some insertion loss. To improve the drawback, we propose a new reflector combined by photonic crystals and glass layer.</p>

  • Thin AMC substrate by applying square patch with semicircle notch

    Shinozaki Ryota, Tamura Jo, Arai Hiroyuki

    DOI CiNii

    Language:English   Publishing type:Research paper (scientific journal)   Publisher:一般社団法人 電子情報通信学会   Joint Work  

    <p>This paper presents a method of thinning an Artificial Magnetic Conductor (AMC) substrate by applying the semicircle notch to the square patch. We analyze the reflection characteristics by changing the arc length of the semicircle. As a result, the frequency where a Perfect Magnetic Conductor (PMC) characteristics appears is shifted to the lower side as the arc length of the semicircle increases. It is confirmed that the proposed method is thinning the AMC substrate thickness about 15% compared with the AMC that has no semicircle notch. Furthermore, it was experimentally confirmed that the thin AMC substrate was thinning by semi-circle notch.</p>

  • Near field EVM estimation in OTA test

    Language:English   Publishing type:Research paper (scientific journal)   Publisher:一般社団法人 電子情報通信学会   Joint Work  

    <p>The EVM (Error Vector Magnitude) measurement is mandatory for radio equipment test. Signals transmitted from multiple antennas give high EVM value due to the phase difference in near field OTA (Over The Air) test. To overcome this difficulty, near field EVM measurement using channel estimation is examined in this paper.</p>

  • Influence of concrete on patch antennas on small ground plane

    Language:English   Publishing type:Research paper (scientific journal)   Publisher:一般社団法人 電子情報通信学会   Joint Work  

    <p>In order to deploy a lot of 5G base stations, there is a method of installing them on utility poles and building walls. In this paper, antennas installed on them for 5G base stations are investigated numerically and experimentally. We examine the minimum ground plane size to remove the influence of concrete and embedded reinforced bars. We also verify the effects on the input characteristics and radiation pattern by measurement.</p>

  • Optical high-gain leaky-wave antenna by using a waffle-iron waveguide

    Kaneoka Shunichi, Iida Wataru, Hashiguchi Hiroshi, Baba Toshihiko, Arai Hiroyuki

    IEICE Electronics Express   18 ( 1 )   20200411-1 - 20200411-4   2021.1  [Reviewed]

    DOI CiNii

     More details

    Language:English   Publishing type:Research paper (scientific journal)   Publisher:一般社団法人 電子情報通信学会   Joint Work  

    <p>This paper presents a comparison of optical leaky-waveguide antennas, i.e., grating waveguide (GWG), waffle waveguide (WWG), and waffle-iron waveguide (WIWG), using both simulations and measurements. WIWG radiates a narrow beam that is tilted by sweeping the incident wavelength, and it possesses a higher antenna gain than GWG and WWG under the same fabrication condition. The reason is due to a slight difference in the effective index along the longitudinal sections, which provides a large aperture size for high antenna gain. We simulate the antenna characteristics and experimentally confirm the high antenna gain.</p>
