An antenna/receiver device including a slow-wave antenna for receiving RF signals. The antenna has a pair of terminals for providing odd-mode antenna excitation of the antenna. A differential-input circuit is connected to the antenna terminals for providing odd-mode, anti-phase current excitation of the terminals and for amplifying the RF signals. A processing circuit is provided for operating on the RF signals and generating an output signal from the RF signals. An optical transducer optically couples the output signal out of the antenna/receiver device. In one embodiment of the invention, the processing circuit comprises a mixing circuit means for mixing the RF signals with a local oscillator signal for generating an intermediate frequency output signal. In an alternate embodiment of the invention, the processing circuit comprises a detector for detecting video information contained in the RF signals.

Millimeter wave fiber-optically linked antenna receiver device

An integrated receiver antenna device comprising a pair of antenna elements providing a spiral antenna for receiving radio frequency signals over a broadband of frequencies with an extended high frequency limit and providing high sensitivity over the broadband of frequencies. The elements each have first and second ends and provide a pair of interwound conductive windings with their first ends positioned proximate to each other at the center of the antenna for providing sensitivity at the high frequency limit of received radio frequency signal, while the second ends of the elements are displaced from the first ends and positioned at the periphery of the antenna. A detector mixer unit is connected between and positioned proximate to the first ends of the antenna elements for deriving radio frequency signals received by the antenna elements and receiving an input signal for providing an oscillating signal at the detector mixer unit for producing an output signal.
