  • Broadband/multi-band horn antenna with compact integrated feed
    Patent number: 8248321
    Abstract: A dual polarization multi-band antenna may include a waveguide horn, a low band feed section, a transition section, and a high band feed section coupled in series. The waveguide horn may be configured to support propagation of electromagnetic waves in a low band and a high band. The low band feed section may include horizontal and vertical feeds and may be configured to support propagation of electromagnetic waves in the low band and the high band. The high band feed section may include horizontal and vertical feeds and may be configured to support propagation of electromagnetic waves in the high band but not in the low band. The transition section may be configured to couple electromagnetic waves in the high band from the high band feed section to the low band feed section and to constructively reflect electromagnetic waves in the low band.
