Abstract The design and development of a wideband dual polarized planar array antenna of 3 × 6 elements in C band is presented. The center frequency is 5.3 GHz. The single radiating element used in the array configuration is of stacked SSFIP. The antenna has been developed for beam pointing of 10° and side‐lobe level better than −15 dB by proper choice of the complex excitation coefficients. The array antenna offers a bandwidth of 20% for a VSWR ratio of 2:1. The measured S parameters and radiation patterns are presented. © 2002 Wiley Periodicals, Inc.
