ABSTRACT:
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.
