PROBLEM TO BE SOLVED: To provide the reception system antenna system capable of long range transmission without the need for any power supply for the reception antenna, without causing a transmission fault such as induced noise, signal leakage, deterioration in signal intensity or the like while avoiding an electromagnetic disturbance such as lightening. SOLUTION: In the reception system antenna system, a couple of reception antennas 1, 2 are provided with transmission sensor heads 3, 4 respectively modulating an incident light into a prescribed luminous intensity and emitting the result as a signal emission light based on a reception signal for a communication radio wave. A polarized light demultiplexer 8 demultiplexes an incident light from a light source 7 and consisting of two linearly polarized lights having polarized planes perpendicularly to each other into two linearly polarized lights and emitting the lights to the sensor heads as the incident lights and photo detectors 9, 10 detect the signal emission light front the sensor heads 3, 4 and converting and outputting them as reception output signals and receivers 11, 12 apply signal processing to the reception output signals from the photo detectors 9, 10. |
