Abstract
An integrated feed broadband dual polarized antenna having a substantially planar support structure and a plurality of symmetrically positioned radiating structures disposed on the first surface of the planar support structure. A plurality of straight, non-interleaving ribs extend substantially perpendicularly from a first and second lengthwise side of each radiating structure. The plurality of straight, non-interleaving ribs extending from the first lengthwise side are complimentary to the plurality of straight, non-interleaving ribs extending from the second lengthwise side of the each radiating structure. Integrated microstrip lines serve as transmission lines to feed. The integrated microstrip lines form an integrated printed circuit infinite balun structure which is inherently frequency independent and provides 180° electrical phase required to feed a 180° rotated radiating structure.
