发明名称 Radio station with circularly polarised antennas
摘要 A radio station including two antennas combined with respective first and second hybrid transmission polarization couplers is disclosed. Each antenna is arranged to generate two orthogonal electric field components in response to two respective quadrature radio signals from the corresponding polarization coupler. The station further includes at least one hybrid distribution coupler with a first output connected to a first input of the first polarization coupler and a second output connected to a first input of the second polarization coupler and at least one radio signal source delivering a radio signal to a first input of the distribution coupler.
