Abstract

This paper presents, for the first time, the implementation of a pattern reconfigurable Yagi-Uda antenna utilizing radio frequency identification (RFID) technology for remote pattern control. The proposed scheme emphasizes the use of wireless communication instead of long metal cables, resulting in improved stability of the antenna’s pattern and return loss. Two low-power consumption single-pole-double-throw (SPDT) switches are employed on a passive resonator, enabling it to function as a director or reflector under the long-range control (up to 25 m) of an RFID reader. Measurement results demonstrate a −10 dB impedance bandwidth of 4.2% and a gain of 7 dBi at 2.41 GHz. The entire system operates with an ultra-low power consumption of 12 μW.
基于射频识别的无线模式可重构八木天线
本文首次介绍了利用射频识别(RFID)技术实现模式可重构的八木宇田天线,用于远程模式控制。所提出的方案强调使用无线通信代替长金属电缆,从而提高了天线图案的稳定性和回波损耗。在无源谐振器上采用了两个低功耗单刀双掷(SPDT)开关,使其能够在 RFID 阅读器的远距离控制(最长 25 米)下充当导向器或反射器。测量结果表明,-10 dB 阻抗带宽为 4.2%,2.41 GHz 增益为 7 dBi。整个系统以 12 μW 的超低功耗运行。
