ABSTRACT:
A low profile, mechanical scan antenna having an aperture assembly and a travel guide assembly is disclosed. The aperture assembly is mounted on a carriage for movement along the travel guide assembly which is rotatably mounted for rotation about an azimuth axis. The travel guide assembly includes an arcuately shaped track and the aperture assembly and carriage move along the inside of the arcuately shaped track through the scanning angle. The arcuately shaped track defines an effective antenna gimbal axis which is in front of the antenna aperture.
