摘要

本文设计了一款宽带、高增益、小型化的方环形贴片天线。该天线由中心馈电的方形贴片、两个寄生方环形贴片和短路贴片组成。利用方环形贴片的TM_(01)和TM_(02)模,可以展宽天线带宽,并实现非常稳定的类似单极子的全向方向图。通过在方环贴片上加载短路贴片,天线的边长减小了约48%,天线的阻抗带宽提高了约26%。该天线的中心频率为5.95 GHz,剖面高度约为0.06λ_0,边长为0.86λ_0,带宽为57.1%(4.25-7.65GHz),最大增益为9.1d B,适用于WLAN无线通信系统。
A wideband high gain compact square ring patch antenna with a monopole-like radiation pattern is presented in this paper. The proposed square ring patch antenna consists of a center-fed square patch, two concentric square ring patches that are shorted to the ground plane through symmetrical shorting walls. The antenna utilizes TM_(01) and TM_(02) modes to broad the impedance bandwidth. By loading the shorting walls, a size reduction of 46% and a bandwidth enhancement of 26% are obtained. The antenna with a low-profile of about 0.06λ_0 achieves a bandwidth of about 57.1%(4.25-7.65GHz) and a peak gain of 9.1 d Bi centered at 5.95 GHz while the side length is 0.86λ_0.
