Wideband antennas are essential for military systems requiring spectrum-agility or multi-functionality. High-gain radar or communication systems require wideband, potentially multi-octave, radiation patterns and VSWR, sometimes with wide angle scanning. Aperture size is constrained by the dimensions of the host platform (e.g. aircraft or naval ship). Low gain mobile communication systems require wideband...
A wideband four-port integrated antenna that is capable of exciting four different radiation patterns is presented. The antenna designated as the magneto-electric multipole consists of four dual-polarized magneto-electric dipoles arranged in a 2 by 2 array configuration above a ground plane. A two layer matching network is used to combine the signals from the four dual-polarized dipoles to produce...
