Patent ID: 7652631

Claim:
An antenna comprising: an array of radiating elements, each radiating element comprising: a pair of conductive fingers each having first and second portions separated by a slot, the first portion being a dipole arm, the conductive fingers separated by a tapered notch having a width at a first end less than a width of a second end; a balun proximate the first end; and wherein, for each conductive finger, the first portion of the conductive finger is capacitively coupled to the second portion of the conductive finger by one or more capacitive elements, each capacitive element selected from the group consisting of: a capacitor; a varactor diode; and conductive material disposed on a dielectric layer, the dielectric layer coupled to the array of radiating elements; a support structure coupled to the array of radiating elements; and a plurality of signal conduits coupled to respective ones of the radiating elements.
