Abstract
An antenna which utilizes a conductive loop shaped element and a conductive tap element. The tap element is located directly adjacent the loop element and is precisely tapped to the loop element at one-half the length of the loop element. Connecting between the output terminal of the antenna and terminals of the loop element and the tap element are a plurality of tuning capacitors. The resulting antenna is small in size and is sensitive to a wide band of frequencies with respect to the center frequency of the antenna.
