    摘要： Systems and methods are disclosed herein for a reconfigurable faceted reflector for producing a plurality of antenna patterns. The reconfigurable reflector includes a backing structure, a plurality of adjusting mechanisms mounted to the backing structure, and a plurality of reflector facets. Each of the plurality of reflector facets is coupled to a respective one of the plurality of adjusting mechanisms for adjusting the position of the reflector facet with which it is coupled. The reflector facets are arranged to produce a first antenna pattern of the plurality of antenna patterns. By adjusting the plurality of adjusting mechanisms, the position of each of the reflector facets coupled to the respective one of the plurality of adjusting mechanisms is adjusted so that the reflector facets are arranged to produce a second antenna pattern of the plurality of antenna patterns.

    摘要： Methods and systems for mitigating disturbances in a dual gridded reflector antenna are provided. An antenna system that includes a first reflective surface, a second reflective surface, and an intercostal ring is provided. The intercostal ring is configured to connect the first reflective surface and the second reflective surface. A baffle is disposed between the intercostal ring and a path of the electromagnetic waves. The baffle is configured to redirect the electromagnetic waves away from the intercostal ring. Alternatively, the baffle is not present, and the intercostal ring is configured to redirect a perturbed portion of an electromagnetic wave away from wave paths of electromagnetic waves reflected by the first reflective surface and the second reflective surface, respectively.
