Correcting Antenna Pattern in Offset Measurements based on Equivalent Dipole Moments

Abstract

A correct antenna pattern is required to ensure the accurate evaluation of antenna design, total radiated power (TRP), total isotropic sensitivity (TIS), receiver sensitivity and etc. However, in some cases the antenna pattern is obtained off-center, which degrades its accuracy. In this paper, an algorithm based on the equivalent dipole moment method is proposed to correct the offset antenna pattern. Detailed derivations and workflow are presented. Besides, the dipole moment extraction is automated by optimization algorithms. A numerical test case is used to benchmark the proposed antenna pattern correction algorithm.
