Hybrid Mode Dielectric Resonators in Microstrip

Rigorous analysis of nonaxially symmetric hybrid modes excited in dielectric resonators on microstrip substrates are presented. The analysis uses the mode matching technique and includes the complex modes, which may exist in the structure, to compute the resonant frequencies and field distributions. Measured and numerical results showing excellent agreement are presented for a sample resonator for several hybrid modes. Numerical results for resonators on microstrip in the millimeter wave region are also included.
