Abstract

A new broadband slot antenna with low cross-polarization is presented. It is realized by introducing metal stubs in the aperture of a conventional bow-tie slot antenna. A spectral domain moment method analysis shows that the cross-polarization can be reduced by about 15 dB. The SWR remains below 1.6 in the bandwidth fupper/flower=2.8. Experimental data are in good agreement with theoretical predictions.

新型低交叉极化宽带缝隙天线
提出了一种新型低交叉极化宽带缝隙天线。它是通过在传统的领结槽天线的孔径中引入金属桩来实现的。谱域矩法分析表明,交叉极化可降低约15 dB。在带宽pper/flower=2.8时,信噪比保持在1.6以下。实验数据与理论预测相吻合。
