Abstract
A dual band antenna system for synthetic vision systems including a slotted waveguide antenna having rows of slots on a front surface, a microstrip patch array antenna overlying the front surface of the slotted waveguide antenna; and at least one transceiver communicatively coupled to at least one of the slotted waveguide antenna and the microstrip patch array antenna.
Claims20
A dual band antenna system for synthetic vision systems, the system comprising:
- a slotted waveguide antenna having rows of slots on a front surface, the slotted waveguide antenna operable to generate a first radio frequency beam at a first frequency;
- a microstrip patch array antenna overlying of the slotted waveguide antenna the microstrip patch antenna operable to generate a second radio frequency beam at a second frequency, wherein the first frequency differs from the second frequency;
- and
- at least one transceiver communicatively coupled to at least one of the slotted waveguide antenna and the microstrip patch array antenna.
1 more element
A method to provide broad-band synthetic vision, the method comprising:
- generating a first radio frequency beam at a first frequency having a small horizontal beamwidth and a large vertical beamwidth, wherein the first radio frequency beam is emitted from a source;
- and
- simultaneously generating a second beam at a second frequency having an equal moderate horizontal beamwidth and vertical beamwidth, wherein the second radio frequency beam is emitted from the source.
A dual band antenna system for synthetic vision systems, the system comprising:
- means for simultaneously generating a first radio frequency beam at a first frequency having a first beamwidth characteristic and a second beam at a second frequency having a second beamwidth characteristic, wherein the first beamwidth characteristic differs from the second beamwidth characteristic;
- and
- means, responsive to the means for generating, for radiating the first and second radio frequency signals.
