Patent ID: 7375685

Claim:
A multiple band electrically small compact planar microstrip antenna, comprising: a narrow radiating strip and a plurality of unlike radiating members are positioned on a microstrip dielectric substrate; each of said plurality of unlike members having a set of unequal dimensions and a greater width than said narrow radiating strip; said microstrip dielectric substrate being stacked on a ground plane; said narrow radiating strip and said plurality of unlike radiating members being connected at a junction; said antenna having an original length and an effective impedance at said junction; each of said plurality of unlike radiating members being configured with a rear edge opposing said junction and being separated by at least one gap therebetween; a connector pin, projecting downward through said narrow radiating strip and said dielectric substrate to said ground plane, shorts said narrow radiating strip; said narrow radiating strip, being folded downward to partially cover said dielectric substrate and said ground plane forms a front edge opposing said rear edges, terminates at said connector pin; and said effective impedance being decreased by said narrow radiating strip and said plurality of unlike radiating members being connected at said junction, results in a reduced impedance allowing said original length to be decreased to an abbreviated length, and each of said plurality of unlike radiating members, having said set of unequal dimensions, provides a distinct resonant frequency in the VHF and UHF regions.
