  • Systems and methods for mitigating disturbances in a dual gridded reflector antenna
    Patent number: 9214736
    Abstract: 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.
    Type: Grant
