The effective dielectric permittivity method is applied, generalized and modified to determine image guide dielectric rods configurations for directional couplers with maximal bandwidth in 3–mm wavelength. Problem of optimization of directional coupling, splitting and summing signals in image guide directional couplers with distributed coupling in frequency range of 80–110 GHz has been solved using CST Microwave Studio code. Results of optimization have been experimentally confirmed.
