Mutual coupling between two dipole antennas with different dimensions placed at arbitrary parallel positions is analyzed using simultaneous integral equations with exact kernels and finite gap feeds. The Nyström method is applied to solve these equations. Self- and mutual-impedances are calculated and compared with the results of the induced electromotive force (EMF) method and Tai's method. The feed structure is accurately modeled, and S-parameters are calculated based on the model. The S-parameters are measured, and the results are compared with the calculated values. They show good agreement, and the validity of this method is verified.
