Abstract :
An antenna pattern correction algorithm that is based on optimization of the signal-to-interference ratio (SIR) is presented. In this method, the antenna pattern of the antenna under test is measured in the far field or a compact range several times at different spatial locations. The method is demonstrated with measurements and simulations in a hologram-based compact antenna test range at 310 GHz.
