ABSTRACT
Waveguide coupler consists of two rectangular pieces in which slot couples power from one waveguide to another. In most of the studies the slot width is neglected. Moreover, the data on coupling for suchcouplers as a function of frequency is not available. As this information is essential in the design of array of such couplers, intensive investigations are carried out to analyze them in order to obtain the data on impedance, reactance, coupling and VSWR as a function of frequency. In the present work, the effect of slot width is taken into account.
