摘要： An antenna system for transmitting and/or receiving radio frequency (RF) signals in multiple frequency bands includes a horn antenna and a feed network. The horn antenna may transmit and/or receive RF signals in multiple frequency bands that are spread over more than an octave bandwidth with at least a 2.44-to-1 bandwidth ratio. The horn antenna includes a throat, an aperture, and an interior surface. The feed network includes a first waveguide section, a first junction, one or more first filters, and a first step-down waveguide section. The first waveguide section can provide a matching network and transmit and/or receive the RF signals in the multiple frequency bands. The first junction can transmit and/or receive the RF signals in first selected band(s) of the multiple frequency bands. The first step-down waveguide section may transmit and/or receive the RF signals in second selected band(s) of the multiple frequency bands.

摘要： A dual-band feed assembly is configured to be coupled to a satellite repeater payload. The dual-band feed assembly includes a transmit filter assembly comprising a transmit pass-band filter configured to reject frequencies outside of a transmit frequency band and a low-pass and harmonic filter configured to reject receive band frequencies and harmonics of the transmit frequency band. The dual-band feed assembly further includes a receive filter assembly comprising a receive pass-band filter configured to reject frequencies outside of a receive frequency band and a high-pass filter configured to reject transmit band frequencies. A multi-port junction couples the transmit and receive waveguide assemblies to a dual-band horn. The dual-band feed assembly also may include receive and transmit test couplers.
