Abstract: This paper deals with design, development and simulation of waveguide type dual directional coupler operating at microwave heating frequency of 2450MHz 25MHz (ISM Band). The Ansoft HFSS13.0 software is used for carrying out the parametric study of performance parameters i.e coupling factor, directivity, VSWR, impedance, return loss etc. of the designed coupler. The simulation of the dual directional coupler is carried out by varying the various parameters of the dual directional coupler for both the forward and reflected ports. These simulation results are verified with experimental results of the fabricated dual directional coupler only for a single measurement because of hardware limitation of the coupler. The emphasize of this paper is on the simulation results of the coupler for variation in loop plate width, loop hole, angular rotation of loop plate from 0 to 350 and coupling gap of the coupler.
