Method And Apparatus For Transmitting And Receiving Multiple Frequency Bands Simultaneously

US Patent:
6329957, Dec 11, 2001
Filed:
Oct 30, 1998
Appl. No.:
9/183355
Inventors:
Donald Shea - Plano TX
Mark Cavalier - Sachse TX
Assignee:
Austin Information Systems, Inc. - Austin TX
International Classification:
H01Q 1300
US Classification:
343756
Abstract:
An antenna feed system capable of simultaneously receiving and transmitting in multiple frequency bands is disclosed. In one embodiment, the feed system comprises a dielectric loading rod, an inner cylindrical waveguide, and one or more outer cylindrical waveguides. The dielectric loading rod lies along a central axis, as do the inner waveguide and outer waveguides. The axis of the inner waveguide and the rod may coincide. Each waveguide may be configured to receive and transmit a different frequency band simultaneously with the other waveguides. In addition, the axes of the outer waveguides also coincide with the central axis. The antenna feed system may further comprise one or more junctions disposed to propagate electromagnet radiation into and out of the inner waveguide and outer waveguides. A method and kit for simultaneously receiving and transmitting in multiple frequencies are also disclosed.
