Patent ID: 7161537

Claim:
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 closed 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 segments being provided between and joining an end of the base segment and the closed end edge of the left and right V-side segments, respectively, the polygonal microstrip patch and the modified V-slot co-operating to provide high-frequency, high-gain dual-band operation.
