In one embodiment, a low profile antenna according to the present invention comprises a balanced transmission line, electronic circuitry, and a parasitic element. The electronic circuitry is coupled to an interconnecting end of the transmission line and operable to direct electromagnetic energy through the transmission line to a terminating end. The parasitic element has a surface that is disposed at a predetermined distance from the terminating end and normal to the central axis such that the surface of the parasitic element covers an opening formed by the terminating end.
