Abstract
An inflatable antenna for use with a buoy at sea is disclosed. Webs in the inflatable compartment of the antenna have parts metallized to form the feed portions of the radiating elements. Areas of the top inner surface of the inflatable compartment are metallized to form capacitive loading portions of the radiating elements. Conductive inner and outer surfaces of the bottom of the inflatable compartment form a ground plane coupled to the sea water. When the elements of the antenna are fed in phase quadrature, the antenna provides hemispherical coverage including sufficient gain at the horizon.
