摘    要: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。

关 键 词:人工电磁结构(AMC)  口径耦合天线  波束控制

Abstract:A novel aperture coupled antenna with artificial magnetic conductor (AMC) structure is presented. The simulated results of a aperture coupled antenna with AMC structure has been given as an example. From the simulated results, the peak radiation of the antenna is shifted at 21° and the gain is 6.4dB at the working frequency 5.5GHz. Furthermore, the parametric studies have been given. As a result, the beam is shifted with the arrangement of the AMC structure. It is shown that the beam can be shifted at 11° with the one arrangement of AMC structure. Base on the antenna element, a 1×2 antenna array is presented. The advantage of array antenna with AMC structure is higher gain and bandwidth, controlled beam performances. The array is shifted at 26° and the gain is 8.47dB at the working frequency 5.5GHz.
Keywords:artificial magnetic conductor (AMC)  aperture coupled antenna  beam controlled
