摘要
采用口径耦合馈电方式设计了一种宽带低剖面微带天线。该天线在覆铜印制板上开缝，通过微带线进行能量耦合，减小了微带线对辐射单元的影响，同时通过调整馈电层与辐射层的间距，达到阻抗匹配的目的。该天线的工作频段为0.93-1.28GHz（VSWR≤2），相对阻抗带宽达到31.6％。
A broadband low profile aperture-coupled microstrip antenna is designed in this paper. The radiated patch is fed by coupling characteristic between a slot on the ground plane and the feeding microstrip line, which reduced the impact of feeding microstrip line. The aperture-coupled feeding method used in this paper is an effective technology which achieves impedance match by adjusting the distance between radiating and feeding layers. The operating band of the proposed antenna is 0.93 GHz to 1.28 GHz （VSWR≤2） and the relative impedance bandwidth is 31.6%.
