Abstract (en)
[origin: EP2226895A2] The antenna has a transducer (7) formed with a transducer connection plug (2) and loop antenna-connection plug (3), where both the plugs are connected to a loop antenna (14) by adjustable-and phase shifting networks (23, 25). Radiation fields of the loop antenna and transducer are superimposed in distant field of the antenna with various phases during the reciprocal operation of the antenna. The transducer includes polarization oriented perpendicular to a polarization of the loop antenna and an orthogonal phase in the distant field.
