摘要：

设计了一种新型毫米波微带双频平面天线阵，该天线阵单元采用凹槽加载中心馈电结构。这种馈电方式恰好等效为在微带贴片上加载了一个电抗，通过调节馈电线的长度，可以获得两个零点，从而使微带天线实现双频工作。基于这种馈电结构和并联馈电网络，制作了平面4 × 4 双频段天线阵。根据实验和仿真结果的比较，二者拟合较好。实测的双频天线阵工作在32.5 GHz和35.7 GHz，天线阵的增益16.25 dB，辐射效率为82%。

Abstract:

A novel dual band microstrip planar antenna array with patch element schemed by using insetfed feed technology is proposed. This feed structure is equivalent to loading a reactance on the microstrip patch. Through adjusting the length of the feeding line, the microstrip antenna obtains two zero points and realizes dual band. Based on this patch element and parallel network, a planar 4×4 dual band microstrip array is fabricated. The experiment and simulation results have a good agreement. The dual band is at 32.5 GHz and 35.7 GHz. The gain of the antenna array is 16.25 dB and the radiant efficiency is 82%.
