Abstract

Systems and methods for providing an antenna enabling hemispherical coverage are disclosed. The system includes a conductive enclosure having an open portion and a closed portion. The system further includes a pair of perpendicularly-disposed dipole antennas. Each antenna of the perpendicularly-disposed dipole antennas includes a pair of conductors extending to a pair of tips disposed outside of the open portion of the conductive enclosure. The system further includes a hybrid coupler having a pair of output terminals coupled to each pair of conductors of each antenna of the perpendicularly-disposed dipole antennas. The hybrid coupler is configured to apply signals of equal magnitude to the each antenna of the perpendicularly-disposed dipole antennas that differ in phase by ninety degrees.
