Abstract
A dual-band antenna with notched cross-polarization suppression can include a symmetrical feed tab, a short circuit leg electrically coupled to the symmetrical feed tab, and symmetrical arms electrically coupled to and extending from opposing sides of the short circuit leg. When a signal with a first frequency energizes the symmetrical feed tab, a combination of the symmetrical feed tab and the short circuit leg can form a first radiating section, but when a signal with a second frequency energizes the symmetrical feed tab, the symmetrical arms can form a second radiating section. The symmetrical feed tab and the symmetrical arms can be oriented such that symmetry of the symmetrical feed tab and the symmetrical arms can yield a cumulative cross-polarization distribution derived from radiation from surface currents on the symmetrical feed tab and the symmetrical arms that theoretically vanishes at a plurality of points in an azimuth plane.
