Effects of choke-load position on radiation properties in double-choked small horn antennas
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.
