1. A microstrip patch antenna element comprising:
- a convex polygonal microstrip patch having at least eight side segments configurable with respect to the performance of the antenna, the patch having a modified V-slot, a closed end of the modified V-slot being substantially parallel to the length of the base of the polygonal microstrip patch, the modified V-slot including;
a base segment defining the closed end;
left and right V-side configurable segments each having a dosed end edge and an open end edge; and
left and right high-frequency control segments configurable to independently control response of the antenna element in two frequency bands, the left and right high frequency control portions being provided between and joining an end of the base portion and the closed end edge of the left and right V-side portions, respectively, the polygonal microstrip patch and the modified V-slot co-operating to provide high-frequency, high-gain dual-band operation.

Abstract
A microstrip patch antenna is provided having a high gain performance with a smaller size compared to existing approaches. The antenna includes a patch having a polygon shape, such as a convex polygon, and a modified V-slot in the polygon patch including high-frequency control segments. Such an antenna has a dual band performance, such as in the Ka and Ku bands. An array of antenna elements is also described, as well as an ultra low profile phased array antenna system.
