  • Antenna system for wireless comunication systems
    Patent number: 5880695
    Abstract: A repeater station having circularly polarized antennas. A diamond panel antenna and a panel antenna are positioned in a back-to-back relationship. Each antenna is circularly polarized. The antennas use "tunnel technology" for isolating the antennas. A chassis forming a recessed portion is provided. A dielectric board is inserted into the recess. Patch elements mounted on a board are inserted into the recess and connected to the dielectric board. The width of the boards are such that a "tunnel" is formed about the periphery thereof. Absorber material is then inserted into the tunnel around the boards. A radome is placed over the recess enclosing the boards and elements.
