摘要
本文在微带天线阵列设计中,采用孔径耦合馈电的办法,将辐射贴片层和馈电网络分层设计,可以获得令人满意的阻抗带宽。实测表明阵列相对带宽可达20%以上,并且这种馈电方式避免了两者共面时由于尺寸限制,馈电网络难于设计的缺点,减小了互耦及交叉极化,是大型微带贴片天线阵列的一种理想结构形式。
A design of broadband microstrip patch antenna array is proposed in this paper. This array is fed by aperture coupling with layered radiate patches and feeding network. Through testing, the impedance bandwidth of the subarray is up to 20%, In addition, this array structure abates the difficulty of the feed line distribution due to the restriction of array plane dimensions, and effectively reduces the influence of mutual coupling and cross-polarization.
