Effect of perturbation by flexible dielectric strip overlay on even and odd mode resonance frequency of microstrip ring resonator is reported. It is seen that change in even and odd mode resonance frequency for proximity coupling obeys cosine and sine like wave function respectively. Even mode resonance frequency tends to vary linearly with width and thickness of strip overlay while for odd mode it is independent of overlay thickness. Empirical equations for both even and odd mode resonance frequencies are reported. Obtained results are compared with the reported direct in-plane coupling.
