Abstract :
Design method of novel multilayer, broadband six port microstrip directional coupler at VHF- UHF range for high power applications is given. Directional coupler is modeled and simulated with the method of moments based planar electromagnetic simulator on a two-layer Alumina substrate. It is shown that the high directivity and desired coupling level of the directional coupler are maintained within 300MHz of bandwidth using the proposed design method in this paper. Results of this work can be used in the design of broadband directional couplers for high power RF/Microwave applications.
