Abstract (en)
[origin: EP0280912A1] A new power supply is specified for a short-wave curtain antenna with phase-controlled rotation of the polar diagram. The power is applied by means of a plurality of transmitters (13, 14). Each transmitter (13, 14) supplies an associated dipole group (10, 11). The rotation of the polar diagram takes place by simultaneous operation of the RF transmitters (13, 14) with a different phase angle. The phase angle is adjusted by means of phase rotating members (17) which are connected upstream of the RF transmitters (14). <IMAGE>
