US Patent:
48780626, Oct 31, 1989
Filed:
Jul 28, 1988
Appl. No.:
7/226018
Inventors:
Tyson S. Craven - Boca Raton FL
Pushpa M. Choriyammakal - Plantation FL
Assignee:
Dayton-Granger, Inc. - Ft. Lauderdale FL
International Classification:
H01Q 142
H01Q 2126
US Classification:
343872
Abstract:
A low profile, low drag, broad-banded antenna system includes four substantially identical antenna elements in intimate contact with a hemisphere of high dielectric constant material. The antenna elements are equally spaced from each other around the hemisphere and are connected to a power divider circuit for reception of incoming signals from a global position satellite having circular polarization. A dielectric phase equalizing member of variable thickness surrounds the antennas in intimate contact therewith for improving the axial ratio particularly at low angles of radiation. The dielectric phase equalizing member is also formed from a high dielectric constant material. A radome of a radio transparent material covers the assembly to provide an aerodynamic configuration and to protect the antenna from the weather. The antenna has a gain from approximately -2. 5 dBic at 10. degree.
