Abstract:
A miniature, multi-branch patch antenna having reduced coupling between antenna elements, comprising:a planar dielectric substrate having a first and a second surface;a plurality of conducting antenna elements disposed on the first surface of the dielectric substrate;a plurality of feed ports for delivering a first signal to, or receiving a second signal from, the plurality of conducting antenna elements, wherein each conducting antenna element is electrically connected to a feed port of the plurality, wherein a different feed port is connected to each of the conducting antenna elements;a ground plane disposed on the second surface of the planar dielectric substrate; anda septum disposed on the first surface of the dielectric substrate between the plurality of conducting antenna elements and in electrical contact with the ground plane, the septum traversing the first surface of the planar dielectric so that each conducting antenna element of the plurality is separated from all other such conducting antenna elements by the septum and wherein none of the conducting antenna elements is surrounded on four sides by the septum.
