3dB Directional Couplers on Image Dielectric Waveguides of 80-110 GHz Frequency Band

摘要

The effective dielectric permittivity method is applied, generalized and modified to determine image guide dielectric rods configurations for directional couplers with maximum bandwidth in 3-mm wavelengths range. Optimization problem of directional coupling, splitting and summing signals in image guide directional couplers with distributed coupling in the 80-110 GHz frequency range was solved using CST Microwave Studio software. Optimization results were been experimentally confirmed
