Dual polarized stacked SSFIP array antenna in C-band for beam-pointing

This paper presents the design and development of a wideband dual polarized planar array antenna of 4 × 6 elements in C-band with a centre frequency of 5.3 GHz. The radiating element is of stacked strip slot foam inverted patch (SSFIP) configuration. The complex excitation coefficients of the antenna have been chosen in order to achieve a fixed beam-pointing by 10° and side-lobe level better than −15 dB. The array antenna offers a VSWR bandwidth of 20% for a VSWR ratio of 2:1. The simulated and measured antenna parameters are presented.
