Abstract

A Fabry-Perot Cavity Antenna (FPCA) has been proposed to achieve considerably wide bandwidth with high gain. An aperture-fed microstrip-patch has been used as the primary radiator where the excitation has been initiated by a specially designed dual-offset feedline. A metal-grid superstrate has been designed for achieving wide matching bandwidth (50%) with more than 10 dBi gain. It promises up to 16.7 dBi gain with satisfactory performance in terms of side lobe level (−15dB to −21dB) and cross-pol isolation (up to 45dB).

一种新型宽带特性法布里-珀罗腔天线

提出了一种具有高增益和相当宽带宽的法布里-珀罗腔天线(FPCA)。采用孔径馈电微带贴片作为主辐射体，其中的激励由特别设计的双偏置馈线发起。为了实现大于10dbi增益的宽匹配带宽(50%)，设计了金属网格层。它承诺高达16.7 dBi增益，在旁瓣电平(- 15dB至- 21dB)和交叉pol隔离(高达45dB)方面具有令人满意的性能。
