Abstract: A temporary microwave horn antenna coupling device is configured for collecting or injecting quantifiable samples of RF energy. The device comprises single electric field probe mounted at the radiating aperture of a radiating payload. The electric field probe can be oriented at 45 degrees to the horizontal and vertical electric fields of a linearly polarized antenna, or oriented for a single linear polarization to the electric field in a circular polarized antenna. The electric field probe is connected to an attenuator and/or lossy cable for reduced reflections and gradient thermal dissipation.

Abstract: A hybrid reflector antenna particularly suited for reflecting a frequency band in a satellite includes a central portion fully reflective to the frequency band. A first annular band is disposed directly adjacent to the central portion. The first annular band is partially reflective to the frequency band. The reflector may include several annular bands having various degrees of reflectivity and thus attenuation. The present invention may be implemented using two such reflectors, one for transmitting and one for receiving in a satellite, for either single or multiple beam applications. This invention offers more compact and lower mass/cost antenna configurations compared to conventional antennas from multiple beam satellite payloads.
