S-LINE CROSS SLOT ANTENNA

摘要

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.
