A novel non-symmetric element is proposed for wideband phased array apertures. The antenna is based on a infinite periodic array of tightly coupled dipoles which are modified to provide an increase in the design degree of freedoms. Specifically, each arm on the dipole is different than the other, or non-symmetric, enabling one to control inductance and capacitance independently. In this case, the arms are similar near the center feed portion, but change shape towards the end of the dipole, forming a ball-and-cup. The non-symmetric qualities can be manipulated for improved UWB performance or operation over a specific bandwidth. A design example for the latter is developed at X-band, specifically 7.75-13.25GHz. Equally important is the balun and matching network, as such, we propose a small feed printed behind the ground plane using twin wire interconnects between the array aperture and balun circuity. The non-symmetric arms can be used to create radically different designs than symmetric ones currently found in literature.
