Thesis On Computer Aided Design of Wide-Band Microwave Components

In recent years there was a notable developmental leap in communications systems operating at microwave frequencies. In the dissertation, the goal is to demonstrate the challenges and to propose solutions that enable the successful design and realization of very wide band microwave components, in particular, microwave directional couplers and filters. Directional couplers are an essential part in microwave systems. They are commonly used for dividing or combining signals. For example they are used in the generation of the desired power division in beam-forming networks for spacecraft antennas. In other applications, they are used for power monitoring. In the dissertation, a comprehensive treatment of wide-band ridge waveguide directional couplers is included. Analysis and design of different configurations and arrangement of couplers realized in ridge waveguides are discussed. A new detailed systematic design procedure for ridge waveguide couplers in the two most used configurations “
