Abstract

The directional coupler is a passive microwave device that can be used for power measurement, it couples power at the input port to the coupled port. It’s design of depends on various parameters such as transmission line used in the design, operating frequency of the device, amount of coupling desired and the required directivity. In this paper a modeling of rectangular waveguide directional coupler is presented numerically. The rectangular waveguide used is WR284, a standard waveguide to operate for the frequency range between 2.60 - 3.95 GHz. For High power application of directional coupler needs lower coupling and high directivity so the amount of coupling is desired to be around 60 dB with minimum directivity of 30 dB is used for the design. The design is simulated with the help of microwave CST studio.
