Ultra-broadband thin planar antenna has a flat elliptical element and a spaced rectangular element co-planar with the elliptical element. The inner conductor of a coaxial cable connects to the elliptical element near a gap between the elements and the outer conductor of the coaxial cable connects to the rectangular element. A housing encases the elliptical and rectangular elements and the transmission line. The antenna functions electrically as an asymmetrical planar dipole having a special configuration or as an elliptical planar monopole with a co-planar finite rectangular ground plane.

A microstrip patch radiator has parallel conductive strips that are connected at opposite ends by conductive connecting strips and separated by slits. The slits are parallel to the direction of the desired patch currents, and perpendicular to the undesired currents, to provide a low impedance path for currents generating the desired antenna polarization, and a high impedance path for orthogonal currents generating the undesired, cross-polarized radiation of the patch.
