Abstract: This paper is to use the spectral-domain technique to perform characteristic analysis of coupled microstrip patch resonators on ferrimagnetic substrates. Our formulation has been validated by comparing our result with the published data and showing an excellent agreement between them. Numerical computations have been performed to obtain dependence of resonant frequency on patch dimensions, offset and separation between the two patches, thicknesses of ferrimagnetic film and substrate. It has been seen that as the length of the patch increases the resonant frequency decreases. The larger the offset between the two patches the lower the resonant frequency. The separation between the two patches strongly affects the resonant frequency. It is also found that the resonant frequency increases as the width of the patch decreases. For the fixed dimensions, separation and offset, a thinner substrate results in a higher resonant frequency, and in contrast, a thinner ferrimagnetic film results in a lower resonant frequency.
