An antenna composed of a conducting body of revolution (BOR) and a parasitic ring shorted to a finite-sized ground plate, designated as the BOR-SPR, is designed for realizing a low-profile base station antenna with a wideband voltage standing wave ratio (VSWR) characteristic. The design of the BOR-SPR starts with a center-fed patch antenna. To match the antenna input impedance to a 50-ohm feed line,...
