Abstract :
Based on the dispersion characteristics of microstrip lines and theory of the coupled transmission line, this paper presents a dispersive delay line which works in the transmission mode and could be used in analog signal processing. This paper theoretically and experimentally confirms that desired group delay responses could be achieved by tuning the lengths of cascaded C-sections in the microstrip structure. The optimized structure is simulated by the electromagnetic simulation software CST Microwave Studio, and a satisfied chirped group-delay is achieved ranging from 0.2 GHz to 3.85 GHz. The experimental prototype is a coplanar design integrated on a microstrip substrate with a shielded aluminum lid above it. The dispersion of the cascaded C-sections has been verified by prototype test and its time-domain analysis.
