Abstract

Characteristics of a rectangular-cavity-backed cloverleaf slot antenna are investigated numerically and experimentally. The method of moments is used to calculate the antenna characteristics where the effects of the cavity are taken into account. The minimum axial ratio of 1.11 dB and the maximum gain of 10.6 dBi are obtained at 2.19 GHz. The frequency bandwidth for the axial ratio (AR) (< 3 dB) and VSWR (< 2) is 2.7%. The symmetrical radiation pattern is obtained with respect to the vertical. The calculated results on AR, VSWR, and radiation patterns are agree well with measured data

用于圆极化的矩形腔背三叶草槽天线

对矩形空腔背置三叶草槽天线的特性进行了数值和实验研究。在考虑空腔影响的情况下，采用矩量法计算天线特性。在2.19 GHz时获得最小轴比1.11 dB和最大增益10.6 dBi。轴比(AR) (< 3db)和驻波比(VSWR)(< 2)的带宽为2.7%。得到了相对于垂直方向对称的辐射方向图。计算的AR、VSWR和辐射方向图与实测数据吻合较好
