Abstract :
A broadband microstrip patch was designed for potential use as an element in a spaceborne multibeam antenna. Its integration in a subarray yields high polarization purity. This structure yields broad bandwidth and low cross-polarization. A subarray of such an element presents a reduced cross-polar level. This type of subarray can be used in a spaceborne (satellite) multibeam array with a maximum deflection of just a few degrees.<>
