设计一种基于人工电磁结构(AMC)的新型口径耦合天线。对加载了AMC结构的口径耦合天线进行仿真。根据仿真结果,天线的工作频率为5.5GHz,辐射的波束指向21°时增益为6.4dB。文中对天线的参数进行分析,波束的偏移角度与AMC结构的有关。将AMC结构变为一排,天线波束可以指向11°。根据天线单元构造1×2的子阵,阵列天线具有更高的增益和带宽,并可以有波束的偏移。天线子阵工作在5.5GHz时天线的波束指向为26°,增益8.47dB。
Design a new type of caliber coupling antenna based on artificial electromagnetic structure (AMC). Simulation of the aperture coupling antenna loaded with AMC structure. According to the simulation results, the working frequency of the antenna is 5.5GHz and the gain of the radiation beam pointing to 21 ° is 6.4dB. In this paper, the parameters of the antenna are analyzed and the angle of the beam offset is related to the AMC structure. The AMC structure into a row, the antenna beam can point 11 °. A 1 × 2 sub-array is constructed from the antenna elements, the array antenna has a higher gain and bandwidth, and may have a beam offset. When the antenna sub-array is working at 5.5 GHz, the antenna beam angle is 26 ° and the gain is 8.47 dB.
