US12540803 - Tactical high power microwave antenna pedestal

An antenna system comprises a reflector subsystem, a rotatable support structure and a support member. The reflector subsystem receives an input beam and reflects the input beam to produce an output beam steered in elevation by an elevation reflector and in azimuth by an azimuth reflector, towards a target. The rotatable support structure is operably coupled to the azimuth reflector and to the elevation reflector and is configured to rotate them simultaneously. The support member comprises a lengthwise portion coupled to the rotatable support structure and an offset portion coupled to the elevation reflector, the offset portion configured to offset the elevation reflector from the lengthwise portion. The offset portion is configured to enable clearance of the elevation reflector during beam steering of the output beam to extreme ends of a range of motion of the elevation reflector.

The patent describes a tactical antenna system designed to steer an output beam towards a target using both elevation and azimuth reflectors that can rotate simultaneously. The design includes a support structure with an offset portion that ensures clearance for the elevation reflector during its full range of motion, enhancing targeting capabilities.

Claim 1

1 . An antenna system, comprising: a reflector subsystem configured to receive an input beam and to reflect the input beam to produce an output beam towards at least one target, the reflector subsystem comprising an elevation reflector having a first range of motion and configured for steering the input beam in elevation and an azimuth reflector having a second range of motion and configured for steering the input beam in azimuth, wherein the output beam is steered in elevation and azimuth towards the target; a rotatable support structure operably coupled to the azimuth reflector and to the elevation reflector and configured to rotate the elevation reflector and the azimuth reflector simultaneously; a first support member comprising a lengthwise portion coupled to the rotatable support structure and an offset portion coupled to the elevation reflector, the offset portion configured to offset the elevation reflector from the lengthwise portion; and a second support member having a first end coupled to the rotatable support structure and a second end coupled to the azimuth reflector; and wherein, during a beam steering of the output beam, the offset portion is configured to enable clearance of the elevation reflector during beam steering of the output beam to extreme ends of the first range of motion of the elevation reflector. a reflector subsystem configured to receive an input beam and to reflect the input beam to produce an output beam towards at least one target, the reflector subsystem comprising an elevation reflector having a first range of motion and configured for steering the input beam in elevation and an azimuth reflector having a second range of motion and configured for steering the input beam in azimuth, wherein the output beam is steered in elevation and azimuth towards the target; a rotatable support structure operably coupled to the azimuth reflector and to the elevation reflector and configured to rotate the elevation reflector and the azimuth reflector simultaneously; a first support member comprising a lengthwise portion coupled to the rotatable support structure and an offset portion coupled to the elevation reflector, the offset portion configured to offset the elevation reflector from the lengthwise portion; and a second support member having a first end coupled to the rotatable support structure and a second end coupled to the azimuth reflector; and wherein, during a beam steering of the output beam, the offset portion is configured to enable clearance of the elevation reflector during beam steering of the output beam to extreme ends of the first range of motion of the elevation reflector.
