Abstract

The design and analysis of a dual-polarization frequency scanning array antenna, operating in a frequency band of 2.7-3.0 GHz, for weather measurement applications are presented. Stacked patch elements are coupled to feed lines through slots etched on the ground plane. A wall of plated holes in the middle of the antenna column is designed to improve the isolation between the two input ports. Both simulation and measurements results confirm that very high polarization purity is achieved.
