ABSTRACT:
Corresponding to transmission data101, phase controller105is controlled to shift a phase of modulated signal103by 0° or 180°. Planes of polarization of modulated signals to be transmitted from antennas106and107are made different from each other corresponding to transmission data101. The electric field strength of a signal received at antenna108changes corresponding to the plane of polarization, thereby voltage value113output from electric field strength detector111varies corresponding to transmission data101, and using this variation, judged result115is obtained. Two results, namely, demodulated data112and judged result115are input to comparing circuit116, whereby the reception apparatus is capable of obtaining received data117with high quality.
