Abstract
A miniature, multi-branch patch antenna suitable for operating in the 1 GHz to 100 GHz frequency range, a method for making same and a communication system using the same is disclosed. In one embodiment, the antenna comprises a planar dielectric substrate, a plurality of conducting antenna elements each having a feed port, a ground plane and a septum located between each conducting antenna element. In a second embodiment, the antenna comprises a planar dielectric substrate, a plurality of conducting antenna elements each having a feed port, a ground plane and a superstrate that is disposed on the plurality of conducting antenna elements and at least a portion of the dielectric substrate. The septum and the superstrate suppress undesirable coupling mechanisms. In a communication system according to the present invention, the miniature, multi-branch patch antenna is coupled to a transmitter and/or receiver.
