Abstract
An antenna for operating over a broadband of frequencies includes an operating radiating elements for radiating radio frequency energy at a selected band of frequencies and a lower radiating element for providing a counter poise to the upper radiating element. An antenna coupler transforms the load impedance of the upper radiating elements and the lower radiating element to a nominal impedance, such as 50 ohms. The coupler element also electronically couples the lower radiating element to the upper radiating element.
