ABSTRACT:
A wideband antenna has a planar conductive tab, a planar ground plane and transmission line. The conductive tab is sub-wavelength in all dimensions and has a top edge that is wider than its bottom end. The width of the conductive tab tapers from the top edge to the bottom end. The ground plane is parallel with and located below the conductive tab. The wideband antenna of the present invention, called a tab monopole, is planar in form enabling it to be readily manufactured using standard printed circuit board methods and facilitating its integration with packages and radio frequency circuitry used to feed the antenna. Operational bandwidths in excess of 40% were realized by this wideband, sub-wavelength antenna.
