ABSTRACT:
There are herein described microwave devices that are mounted at the output ends of circularly polarized horn antennas of a microwave antenna array. The devices act as coupling compensators between the horns, and also function as singular or dual polarization trimmers to create very low axial ratio circularly polarized antenna array patterns through a broad angular range. In each of these devices, a parasitic element is disposed on a planar substrate that is orthogonally positioned with respect to the direction of propagation from the horn antennas.
