Abstract

In this paper, a hexagonal shaped frequency reconfigurable patch antenna is proposed that can be deployed in WLAN, mobile satellite communication and radio navigation. In this reconfigurable patch antenna design, a hexagonal patch is connected to two nearby rectangular patches via PIN diodes allowing it to switch between five different frequencies( i.e., 5.27 GHz, 2.16 GHz, 5.45 GHz, 2.88 GHz and 5.76 GHz ). The proposed design provides 6.38 dBi gain and 435 MHz bandwidth when both diodes are in OFF state. Ansys HFSS is used for antenna simulation and a prototype with necessary biasing components and circuit has been fabricated and tested using Keysight Vector Network Analyzer N9925A.
用于WLAN应用的频率可重构六角形贴片天线
本文提出了一种六角形频率可重构贴片天线,可部署在无线局域网、移动卫星通信和无线电导航中。在这种可重构贴片天线设计中,六角形贴片通过PIN二极管连接到附近的两个矩形贴片,允许它在五个不同的频率(即5.27 GHz, 2.16 GHz, 5.45 GHz, 2.88 GHz和5.76 GHz)之间切换。当两个二极管处于OFF状态时,所提出的设计提供6.38 dBi增益和435 MHz带宽。采用Ansys HFSS对天线进行仿真,并制作了带有必要偏置元件和电路的样机,并使用Keysight矢量网络分析仪N9925A进行了测试。
