Abstract

A printed compound air-fed array antenna with hexagonal configuration is developed, which consists of a stacked-patch radiator, an FSS-cover an AMC-base both with square elements arranged as a hexagonal grid respectively. By means of optimal option for all the structural parameters individually, a broadband prototype is designed at 10 GHz, the peak-gain of 17.11 dBi is performed by hexagonal aperture with side-length of 45 mm (1.5 wavelength); a common frequency bandwidth of 8.20 % for VSWR ≤ 2.0:1 and gain-drop ≤ 2 dB and SLL ≤ −15 dB is obtained by simulation. They are verified by measured results as 16.59 dBi peak-gain and 7.54 % common bandwidth.
