Microstrip Wilkinson power divider with Enhanced isolation and Miniaturisation for Defence applications

The design of modified Wilkinson power divider is done by dividing Quarter wavelength transmission line into two, in-between that complex isolation component and compensation capacitor is added. Complex isolation component provides physical separation and electrical isolation between two output ports. It consist of parallel or series RLC circuit is chosen to realize. To get the widest bandwidth, inductors in both components are omitted. In the proposed method, Parallel RLC circuit is chosen because of easy design and soldering. A coupled line section with a compensation capacitor is introduced to reduce the circuit size and also compensates the coupling effect produced by the coupled line section. The circuit is designed with the operating frequency 1GHz on CGK-500 substrate with thickness 1.965 and simulated using ADS software.
