Abstract
The present invention is directed to an antenna system which may serve as a common antenna for multiple avionics systems implemented on-board an aircraft. The antenna system provides horizontal and vertical polarization functionality, while providing high isolation between a first input port of a coupler of the antenna system (the first input port being connected to a first avionics system) and a second input port of the coupler (the second input port being connected to a second avionics system).
