ABSTRACT:
An antenna is provided which includes a primary folded dipole element and a feed for the primary folded dipole element. The primary folded dipole element is operable to resonate at a first frequency range. A parasitic dipole element is located within the primary folded dipole element and is spaced therefrom. The parasitic dipole element is operable to resonate at a frequency range that is higher than the first frequency range. Additional parasitic dipole elements may be located within the primary folded dipole element and spaced therefrom to resonate at different frequency ranges.
