  • High Gain Beam Steering Optical Leaky Wave Antenna for 6G Optical Wireless Communication

    Language:Japanese   Publishing type:Research paper (scientific journal)   Joint Work  

    To realize high data transmission speed for large data traffic, optical wireless communication has gained attention for 6G. For antenna operating in optical frequency bands, high gain is required owing to high propagation loss. In addition, the beam width becomes very narrow by high gain, thus, beam steering is also required to link between the transmitter and the receiver. This paper presents gain enhancement of optical leaky wave antenna, its excitation method and prospects.

  • EIRP Estimation Using a Phase-less Spherical Near Field Measurement

    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 far field estimation method using a phase-less spherical near field data, which overcomes OTA test problems such as measurement cost and time. The method is based on matrix equation of radiation from wire grid model by introducing three techniques such as a wire grid source model, an adjustment of matrix equation, and the optimal sampling method. We confirm that far field estimation is conducted with high accuracy by introducing three new techniques in simulation.</p>

  • Scanning Range Expansion and Gain Enhancement of Array Antenna by Dielectric Lens

    Sugaya Satoshi, Arai Hiroyuki

    IEICE Communications Express   advpub ( 0 )   2022.8  [Reviewed]

    DOI CiNii Research

     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>In this paper, we propose a lens that enables array antennas to expand their scanning range and achieve high gain. Millimeter-wave band requires beam scanning with high gain. In addition, the demand for wide-angle scanning is increasing. Therefore, we propose the lens that enables these demands. The scanning angle of the array antenna, which consists of eight patch antennas, is 0° to 41° at 28GHz. The scanning angle is increased by about 1.5 times from 0° to 62° by the proposed lens. The realized gain has also been significantly improved, achieving more than 21 dBi at all scan angles.</p>
