SIMPLE FORMULA AND ITS EXACT ANALYTIC SOLUTION OF MUTUAL IMPEDANCE FOR NONPLANAR-SKEW DIPOLES

The analysis of an antenna mutual coupling is a significant issue for designing the wireless communication system especially includes an array mutual coupling problem. The accurate analysis of the mutual coupling between antennas is needed. Accordingly, several methods for the mutual impedance calculation of dipoles have been studied in cases of coplanar-skew and nonplanar-skew. This paper proposes an exact and simple method for analyzing the mutual impedance between two arbitrarily located and slanted dipoles using the modified induced EMF method; their expressions and the exact analytic solution. The proposed formula and their closed-form solutions are verified by numerical solution using HFSS and give good agreement.
