  • Abstract
    The design of a dual-polarized microstrip patch sub-array to be used as the radiating element in an array for the CASA Off-the-Grid radar system is presented. The sub-array consists of four microstrip patches with dual feeds and oppositely fed to reduce the cross-polarization levels. Simulation results in demonstrate a 7% bandwidth at 9.4 GHz, port isolation of 30 dB, and cross-polarization levels of 27 dB at broadside.
