Patent ID: 7183977

Claim:
An antenna comprising: a first radiating element disposed on a first side of an insulating substrate; and second radiating elements disposed on the first side of the insulating substrate; and a coplanar waveguide feed line disposed on the first side of the insulating substrate, wherein the coplanar waveguide feed line extends across the first side from a feed point between the second radiating elements to couple with the first radiating element, the coplanar waveguide feed line and the second radiating elements defining a coplanar waveguide structure of the coplanar waveguide feed line, wherein the first radiating element has a fanned-out shape, and wherein the second radiating elements together have a fanned out shape positioned in opposition to the first radiating element, and wherein the first and second radiating elements have a spacing therebetween having dimensions selected to impedance-match the antenna.
