ABSTRACT:
An antenna is provided equipped with a device which rotates the direction of the rectilinear polarization of a wave transmitted to a receiver (or transmitted by a transmitter) associated with the antenna, with respect to this same wave such as it is received by the antenna (or transmitted by the antenna). The device is formed from a square cross-section wavequide which is twisted in steps and which steps may be adjustable and which is twist guide inserted in the primary source of the antenna, between the horn of the antenna and the receiving (or transmitting) means associated with the antenna.
