摘要

为了提高毫米波线性并行馈电网络贴片阵列天线的性能，提出了一种新的人工磁导体设计方案。AMC用作寄生贴片，放置在70 GHz频率的两种条件下。第一种情况是寄生AMC贴片靠近天馈线，第二种情况是寄生AMC贴片放置在天线贴片的中心。详细介绍了AMC和阵列天线的设计，并与无寄生AMC贴片的天线阵列进行了仿真比较。结果表明，与无寄生AMC贴片的天线阵列相比，两种条件下的增益分别提高了4.4%和5.8%。第一种条件下的带宽比第二种条件下和无寄生AMC贴片的天线带宽提高了20%。第二种情况下的天线副瓣比第一种情况下和无寄生AMC贴片的天线副瓣大。第二种情况下的效率比第一种情况和无寄生AMC的天线提高了2%。

Millimeter-Wave Parasitic AMC Patches on the Array Antenna

A new design of artificial magnetic conductor (AMC) is recommended in order to improve the performance of a millimeter-wave (mmW) linear parallel feed network patch array antenna. An AMC is used as parasitic patches that are placed in two conditions at a frequency of 70 GHz. The first condition is the parasitic AMC patches are that placed closely to the antenna feed line and the second condition is the parasitic AMC patches that are placed at the center of the antenna patches. Details of the AMC, and array antenna design are explained, and the simulation results collected with a comparison to an antenna array without parasitic AMC patches are presented. It is observed that the gain of both conditions are increased by 4.4 % and 5.8 %, respectively, compared to the antenna array without parasitic AMC patches. The bandwidth of the first condition is enhanced by 20 % compared to the second condition and antenna without parasitic AMC patches. The sidelobe of the second condition is larger than the first condition and antenna without parasitic AMC patches. The efficiency of the second condition is improved by 2 % compared to the first condition and antenna without parasitic AMC.
