REFLECTIVE-TYPE ANTENNA BAND AND POLARIZATION SELECTABLE TRANSCEIVER USING A ROTATABLE QUARTER-WAVE PLATE |
摘要 |
A low-loss band and polarization-selectable gender-selectable transceiver for use with a reflector-type antenna suitable for the E-band frequency allocation as well as other RF bands in which the upper and lower bands are separated by a stop band. In addition to providing the gender-selectable combination of the upper and lower bands for transmit and receive, this topology allows for the selection of transmit and receive polarizations. A transceiver may transmit and receive on the same or on orthogonal polarizations. Paired transceivers may transmit on the same or on orthogonal polarizations. This is accomplished by integrating a rotatable polarizer (e.g. a wave plate) and a polarization duplexer (e.g. an orthomode transducer) in a FDD (Frequency-Domain Duplexed) system. The rotatable polarizer allows for selection of both transmit and receive bands and polarizations. |
