ANTENNA FOR WEAK RADIO WAVE TWO-WAY TRANSMISSION/ RECEPTION

摘要

PURPOSE:To send/receive a signal efficiently in two-ways with a weak radio wave by using an inexpensive installation without need for an additional function to a next-stage of the antenna. CONSTITUTION:A weak radio wave is emitted from a stationary station through a transmission leakage coaxial cable 26 with a low radiation efficiency and a mobile station side receives the weak radio wave through a leakage coaxial cable 24 for reception with a high radiation efficiency and demodulated by a MODEM connecting to the leakage coaxial cable 24. Then the weak radio wave is emitted from a mobile station through a transmission use leakage coaxial cable 28 with a low radiation efficiency and received by a reception leakage coaxial cable 22 at the stationary station and demodulated by a MO DEM connecting to the leakage coaxial cable 22. The cables 22, 26 and 24, 28 are respectively integrated.
