Abstract
An antenna having a radiator comprising a conduct in a closed path driven by a plurality of microstrips connecting the radiator to a common, single feed and to a ground plane, with the radiator lying in a plane parallel to that of the ground plane. The radiator may be annular, with the feed located in its center. The relative location of the feed on the microstrips allows a lower input impedance to be leveraged to match a higher load impedance of the radiator. A single-ended input drives all points of the radiator substantially in phase. In another embodiment, the antenna comprises a cylindrical choke one-quarter wavelength in length placed around the coax feed and connected to the underside of the ground plane.
