    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.

    摘要： A frequency selective medium that is adapted to receive an incident electromagnetic radiation at an angle of incidence of about 45.degree. has two arrays of conductive elements on opposite parallel surfaces (20, 22) of a dielectric substrate. In one embodiment, the conductive elements are cross-dipoles (6) each having a horizontal dipole (10) and a vertical dipole (8) of different lengths and widths. In another embodiment, the conductive elements comprise a plurality of conductive gridded rectangular loops (40). The frequency selective medium allows incident waves that are within a passband of transmit frequencies to transmit through the medium, and reflects waves at frequencies within a stopband adjacent the passband. In other embodiments, meanderline polarizers (28) are added to cross-dipole and gridded rectangular loop frequency selective media to circularly or dual-linearly polarize incident linearly polarized waves.

    摘要： A re-polarization means for generating circular polarized electro-magnetic waves using single or multi-layer lattice structure mounted in front of a radiation aperture with the lattice structure comprising a plurality of conductors which extend parallel to each other and/or meander shaped and wherein the lattice structure has one or more additional layers which are closer to the radiation aperture and which has a plurality of parallel conductors but that are inclined by an angle of 45.degree. relative to the direction of the conductors mounted on the other layers which meander. Additionally, orthogonal polarization suppression is achieved with the apparatus of the invention. The invention can be applied to a radom of a target tracking radar antenna, for example.
