METHOD AND APPARATUS FOR MOUNTING A ROTATING REFLECTOR ANTENNA TO MINIMIZE SWEPT ARC |
摘要 |
An apparatus and method for mounting a rotatable reflector antenna system on an outer surface of an aircraft which minimizes a swept arc of a main reflector. This allows the effective frontal area of the main reflector to be reduced such that a radome with a smaller frontal area can be employed to cover the antenna system. The main reflector is rotated about an azimuth axis which is disposed forward of an axial center (i.e., vertex) of the main reflector. In one embodiment the azimuth axis is located in a plane extending between the outermost lateral edges of the main reflector, which define the aperture of the antenna. In another embodiment the azimuth axis is located forward of the outermost lateral edges of the main reflector. In further embodiments the azimuth axis of rotation is located in between a subreflector and a feed horn of the antenna, or in between the vertex of the main reflector and the subreflector. |
