Patent ID: 8090411

Claim:
A lens-based millimeter wave transceiver for use in wireless communication systems operating in the E-band spectrum consistent with the FCC rules regulating the 71-76 GHz and 81-86 GHz bands said transceiver comprising: A) a single lens adapted for transmission of millimeter radiation to form communication beams in one band of either a band of about 71-76 GHz or a band of 81-86 GHz and for collection and focusing of millimeter wave radiation from communication beams in the other of the two bands, B) a feed horn adapted to broadcast millimeter radiation through said single lens and to collect incoming millimeter wave radiation collected and focused by said single lens, C) a millimeter wave diplexer adapted to separate incoming and outgoing millimeter wave radiation; wherein said transceiver is adapted to produce outgoing beams with a minimum 3 dB divergence angle of 1.2 degrees, a minimum antenna gain of G=43 dBi, side lobe reduction between 1.2 degrees and 5 degrees of G-28, and side lobe reduction of 35 dB between 5 and 10 degrees off axis.
