Mutual Coupling from Far Field Measurements

摘要

A theory for mutual coupling between two dimensional canonical minimum scattering antenna is reviewed. Expressions for self and mutual impedance are formulated in terms of the measurable far field radiation diagram. The case of two identical aerials is considered in some detail. The constraint of band limitation is applied to the antenna pattern function to facilitate the required analytic continuation thereof. Numerical analytic continuation is addressed whereby sampling proximates and Miller-Tikhonov regularization schemes are examined. (Author)
