Abstract
A dual polarized wave-guide notch antenna array is disclosed. The device comprises a feed section having at least two input transmission lines, a feed/wave-guide interface providing an aperture for transferring a radio frequency electromagnetic wave between the feed section and a wave-guide mode in a wave-guide section having ridges. The wave-guide section transfers energy between the feed/wave-guide interface and a tapered notch section, thereby gradually adjusting a created electromagnetic field towards free space conditions.
