本文提出了一种高增益宽阻带滤波天线。在Ka频段宽带天线的基础上，设计了一种在馈电贴片上刻蚀的简单U形槽，在34.0-35.5GHz的频率范围内，实现了阻带宽度为1.5GHz，平均增益下降3dB的宽带天线。然后设计了两个不同有效长度的U形槽，得到了一个在32.3-34.4GHz范围内阻带宽度为2.1GHz的二阶阻带滤波天线。
In the paper, a wide stopband filtering antenna with high gain is proposed. Based on a wideband antenna for Ka band, a simple U-shaped slot is designed etching on the feeding patch, to achieve one stopband width of 1.5 GHz with average gain down 3 dB, in the range of 34.0-35.5GHz. Then two U-shape slots with different efficient length are designed, resulting in a two order stopband filtering antenna, which has a stopband width of 2.1GHz, in the range of 32.3-34.4GHz.
