Abstract :
The analysis of an edge coupled strip inset dielectric guide, based on the extended spectral domain approach, is presented. Effects of various structural and material parameters on propagation constants and characteristic impedances are investigated. Due to many structural and material parameters available, a wide fundamental mode bandwidth and a broad range of impedances can be achieved, leading to great flexibility. The dispersion in fundamental mode propagation constants and impedances is found to be very low. With suitable choice of different permittivities for two dielectric layers, the same propagation constants for two fundamental modes can be obtained, which are desirable for directional coupler applications
