摘要

为了减小定向超宽带天线的交叉极化，设计了一种电磁极化滤波器。过滤器是一个矩形的盖子，两边是固体金属片，顶部和其他侧面是印刷的金属条。该帽使整个结构的高度增加了5mm，同时在8ghz至11ghz频段内将最大交叉极化电平降低了7db。所得到的天线在频带上的最大交叉极化电平为-20 dB。

Cross-polarization reduction in a directive ultra-wideband antenna using electromagnetic polarization filter

An electromagnetic polarization filter (EMPF) is designed to reduce the cross-polarization of a directive ultra-wideband (UWB) antenna. The filter is a rectangular cap with solid metal sheets on two sides and printed metal strips on the top and other sides. This cap increases the height of the whole structure by 5 mm while reducing the maximum cross-polarization level by 7 dB over the frequency band 8 GHz to 11 GHz. The resulting antenna has a maximum cross-polarization level of -20 dB over the frequency band.
