摘要

设计了h槽截断贴片激励圆极化短逆火天线(SBA)。新设计的SBA包含h形槽和截断贴片，由单进给探针馈送。它还包括在副反射器高度的寄生环。结果表明，h形槽截断贴片可实现4.0%的电压驻波比(VSWR <- 10dB)，轴比(AR)带宽7.71%(≤3dB)，增益14.3 dBi。说明了天线的结构，并在2.4 GHz下进行了仿真。

Short backfire antenna excited by H-slot truncated patch

H-slot truncated patch is designed to excite a circularly polarized short backfire antenna (SBA). The novel design of SBA contain H-shaped slot with truncated patch fed by single feed probe. It also consists of parasitic circular ring at the height of sub-reflector. It is demonstrated that H-shaped slot truncated patch can achieve a voltage standing wave ratio (VSWR) bandwidth of 4.0% (VSWR < −10dB) with a axial ratio (AR) bandwidth of 7.71% (≤ 3dB) and a gain of 14.3 dBi. The structure of antenna is explained and the simulation results are obtained at 2.4 GHz.
