Abstract
A formula is proposed for measuring the antenna factor of an offset-fed parabolic reflector operated as a compact antenna range (CAR) by considering the plane-wave approximation and field-distribution in the collimated region. The antenna factor is determined from the half power beamwidth (HPBW) of the feed, the physical geometry of the reflector and a field-distribution correction factor. The proposed formula is in good agreement with the measured results using a standard double-ridged horn antenna as the feed. The formula can be used to design CARs for EMC applications.
