Abstract :
Results of experiments conducted for the purpose of investigating the effects of the choke position on the beam circularity and the crosspolarisation properties in double-choked small horn antennas are presented. It is shown that the value of the maximum crosspolarisation can be suppressed below ¿37 dB by properly displacing the choke position from the circular waveguide aperture.
