Abstract :
The analysis and synthesis of directional couplers on ridged waveguides through small circular apertures in common wide wall is carried out. Electromagnetic fields and cutoff wave numbers are calculated by method of partial regions including field singularities at the edge. For calculation of couple parameters the Bethe´s quasi-static theory is used. The calculation results of 10 dB and 20 dB directional couplers are given.
