Özet

A new and simple dynamic permittivity expression for the circular disk microstrip structure including air gap is determined and used in the resonant frequency calculation. The formulation provides the best fit with the experiments for fundamental and higher order modes. The proposed dynamic permittivity expression is valid for thin and thick gaps and is well suited to be used in the computer-aided design of the tunable characteristics of the structure.
