Abstract

The expression of calculation of the waveguide-stripling-coaxial line directional coupler, Coupling is through small apertures in the form of a circular hole, is derived. The relationships between Technology parameters with the geometric of the directional coupler are analyzed in detail, the numerical results indicate that, in order to get acceptable of coupling coefficient and directivity, ones may not only change the size of the small hole and rotate the probe in the waveguide - waveguide directional coupler, but also the size of stripline as well as the coupler position.
