    摘要： Various aspects of the disclosure provide low index metamaterials. The low index metamaterials may be used to form soft and/or hard electromagnetic (EM) boundaries to facilitate desired EM performance or propagation in applications including feed horns, spatial feed/combiners, isolation barriers between antennas or RF modules, and reduced radar cross-section applications. In one aspect, a low index metamaterial comprises a dielectric layer and a plurality of conductors on a surface of the dielectric layer, embedded in the dielectric layer or both, wherein the low index metamaterial appears as a medium having a dielectric constant less than one with respect to electromagnetic waves at predetermined frequencies and propagating at grazing angles with respect to a surface of the low index metamaterial.

    摘要： An antenna array comprises two or more antenna elements. Each of the two or more antenna elements is configured to scan within a field of view. Each of the two or more antenna elements is further configured to transmit or receive a signal. The antenna array also comprises a metamaterial lens coupled to the two or more antenna elements. The metamaterial lens is configured to distribute the signal according to a sinc-like distribution over an aperture of the antenna array.

    摘要： A system for interference suppression onboard a satellite includes a beamforming module that processes radio-frequency (RF) signals originated from a plurality of antenna elements of an array antenna to generate multiple analog signals. At least one of the analog signals is an anti-interference signal. Analog-to-digital converters convert the analog signals to a number of digital signals. A processing module processes the digital signals to generate a phase and amplitude control signal. A summation module generates one or more composite signals with reduced interference.

    摘要： A horn for direct radiation or for use as a reflector feed is for operation at disparate frequencies. The horn has a conventionally LSE1,0 distribution at the lower of the two frequencies, and both LSE1,0 and LSE3,0 modes, phased for improved gain, at the higher frequency. The LSE3,0 mode is generated by an H-plane step, and the appropriate phasing, together with improved gain at the lower operating frequency, is achieved by the use of dielectric loading adjacent the E-plane walls of the phasing section of the horn.

    摘要： A concentric arrangement of multiple spacecraft antennas mounted symmetrically about the yaw axis of rotation or center of gravity of the spacecraft that provides the capability for spacecraft with multiple antennas to maneuver without introducing errors into navigation signals and without adding complexity to the spacecraft and/or remote terminals. An arrangement of multiple spacecraft antennas comprising a first antenna array mounted on a spacecraft bus, the first antenna array having a center located on a yaw axis of the spacecraft and a second antenna array mounted on the spacecraft bus, the second antenna array having a coincident or overlapping frequency band as the first antenna array and mounted symmetrically about the yaw axis of the spacecraft in a central portion of the first antenna array so as to be concentric with the first antenna array.
