RADIO STATION WITH CIRCULARLY POLARISED ANTENNAS

摘要

A radio station including two antennas (10, 12) combined with respective first and second hybrid transmission polarisation couplers (143, 144) is disclosed. Each antenna is arranged to generate two orthogonal electric field components in response to two respective quadrature radio signals from the corresponding polarisation coupler. The station further includes at least one hybrid distribution coupler (141) with a first output (C1) connected to a first input (A3) of the first polarisation coupler (143) and a second output (D1) connected to a first input (A4) of the second polarisation coupler (144), and at least one radio signal source (T1) delivering a radio signal to a first input (A1) of the distribution coupler (141).
