  • RF and IR bispectral window and reflector antenna arrangement including the same
    Patent number: 6307521
    Abstract: A reflector antenna arrangement can transmit and receive both infrared (IR) and millimeter wave (RF) radiation. The arrangement includes a main reflector (1), a subreflector (2), an IR feed system (4), an RF feed system (3), a radome (5), and a bispectral window (6) arranged in an opening provided in a central area of the main reflector (1). The RF feed system is oriented so that the RF radiation path includes a double reflection from the subreflector and from the main reflector, while the IR feed system is arranged directly behind the bispectral window so that the IR beam path extends directly through the bispectral window without reflecting from the main reflector or the subreflector. The bispectral window has a high reflectance for the RF radiation and a high transmittance of the IR radiation.
