The letter describes a hemispherical coverage antenna for spacecraft. The antenna has excellent impedance, axial ratio and gain characteristics over a +or-10% frequency bandwidth. This type of antenna is applicable to telemetry and control for spacecraft, missiles, aircraft, Inmarsat small terminals for ships and boats, and M-sat ground terminals in cars and satellite systems, where high efficiency performance of hemispherical radiation is required.
