Abstract

In this paper, a wideband monopole antenna with reconfigurable frequency notch through wireless local area network (WLAN) (5.15-5.35GHz and 5.725-5.825GHz) or future wireless fidelity 6GHz (Wi-Fi-6E) (5.925-7.125GHz) band for C-band applications is presented. The conventional/basic monopole antenna consists of four-leaf clover antenna structure with cascaded feeder and Defected Ground Structure (DGS). The basic antenna is designed and then simulated using Computer Simulation Technology (CST) and High-Frequency Structure Simulator (HFSS) readymade software programs. The antenna covering an operational bandwidth extends from 4.2GHz to 9.2GHz while the gain is around 4.0dBi. Two simple resonator conductors are added near the thin feeder of antenna to realize the notched frequency. The rejected frequency within WLAN or Wi-Fi 6E bands is controlled by the resonator conductor lengths, so Positive-Intrinsic-Negative (PIN) diodes switches are inserted to achieve the required length for each rejected band. Finally, each of the basic antenna and the proposed notched antenna are fabricated and measured. The measurement results are in good agreements with the simulated results of CST and HFSS, providing good antenna performance and sharp notches with good rejection values.

一种适用于C波段应用的可重构陷波带单极天线

本文提出了一种通过无线局域网(WLAN) (5.15-5.35GHz和5.725-5.825GHz)或未来无线保真度6GHz (Wi-Fi-6E) (5.925-7.125GHz)频段用于c波段应用的可重构频率陷波的宽带单极天线。传统/基本单极天线由带级联馈线的四叶三叶草天线结构和缺陷地面结构(DGS)组成。设计了基本天线，并利用计算机仿真技术(CST)和高频结构模拟器(HFSS)软件进行了仿真。天线覆盖的工作带宽从4.2GHz扩展到9.2GHz，增益约为4.0dBi。在天线的细馈线附近增加两个简单的谐振腔导体来实现陷波频率。WLAN或Wi-Fi 6E频段内的拒绝频率由谐振器导体长度控制，因此插入正本性负(PIN)二极管开关以达到每个拒绝频段所需的长度。最后，对每个基本天线和所提出的陷波天线进行了制作和测量。测量结果与CST和HFSS的仿真结果吻合良好，天线性能良好，陷波锐利，抑制值良好。
