ABSTRACT:
A dual frequency batwing antenna includes a larger batwing with smaller UHF batwings located in substantially the same plane but within a vacant space provided by the larger batwing. The smaller batwings are also co-linear so there is no inductive coupling. Thus a pair of radio frequency signals are radiated from a common aperture.
