Microstrip Coupled Line Directional Coupler Design via Block-Based Microwave Training Kit

This paper presents the design of a single section and multi-section microstrip coupled line directional couplers with the brick-based microwave component design methodology. The brick shaped metal and dielectric cells enable the design of microwave components directly in front of a network analyser. Students can calculate, design, build, measure and iterate their design easily in time-limited microwave laboratory classes. The measurement and simulation results with the free circuit simulator software Qucs [1] are compared throughout the paper. The design of brick-based microwave components in microwave laboratory lectures increases the microwave education quality.
