1. A cross slot broad band cavity backed antenna, comprising:
- a radiating element comprising a plurality of radiating slots configured in a radiating cross slot layer;
a first cavity configured in a first spacer layer, the first spacer layer positioned adjacent one side of the radiating layer;
suspended feed transmission lines equal in number to the plurality of radiating slots supported on a transmission feed layer, the transmission feed layer positioned adjacent to the first spacer layer;
a second cavity configured in a second spacer layer, the second spacer layer positioned adjacent to the transmission feed layer; and
a ground plane comprising a copper clad surface on a ground plane layer, the ground plane layer positioned adjacent the second spacer layer.

Abstract
A cross slot broad band antenna comprises a five layer configuration including a radiating element cross slot layer having a plurality of radiating slots. Positioned adjacent one side of the radiating element layer is a first spacer layer configured to define a cavity. An S-line feed layer having feeds equal in number to the plurality of radiating slots is positioned adjacent to the first spacer layer. A second spacer layer is positioned adjacent the S-line feed layer and is configured to define a cavity. The fifth layer, a ground plane layer, has a copper clad surface and is positioned adjacent the second spacer layer.
