Claim:
1. An antenna, comprising: a substrate formed of a non-conductive material having a front and a back; a ground plane disposed on said front of said substrate; a wideband radiating element disposed on said front of said substrate having one end connected to an edge of said ground plane, said substrate defining a gap between the ground plane and the wideband radiating element, the gap having a width of less than 1/80 of a predetermined wavelength; and a single elongate feed arm disposed on said back of said substrate opposite of the gap defined by the substrate on the front of said substrate, said single elongate feed arm not galvanically connected to said wideband radiating element, said single elongate feed arm feeding said wideband radiating element said elongate feed arm having a maximum width of 1/100 of the predetermined wavelength, wherein the wideband radiating element further comprises: a first portion having a first end and a second end, the first end of the first portion galvanically connected to the ground plane, the first portion defining the gap between the ground plane and the wideband radiating element; a second portion substantially perpendicular to the first portion, the second portion having a first end and a second end, the first end of the second portion being galvanically connected to the second end of the first portion; a third portion substantially perpendicular to the second portion, the third portion having a first end and a second end, the first end of the third portion being galvanically connected to the second end of the second portion; and a fourth portion substantially perpendicular to the third portion, the fourth portion having a first end and a second end, the first end of the fourth portion being galvanically connected to the second end of the third portion, the second end of the fourth portion arranged in a direction of the ground plane.
