Abstract :
The paper presents design, simulation and measurement of microstrip filters based on meander folded hairpin resonators. For the design purposes, the coupling coefficient of the coupled resonators of different topologies is investigated. Each topology is simulated in full-wave electromagnetic simulator and the coupling coefficient is extracted. Design graphs for the coupling coefficients are presented. Based on the simulation results, two design examples are carried out. The first design example is 4 pole cross coupled Chebyshev filter presenting two symmetrical attenuation poles. The second example is 4 pole classic Chebyshev filter. There is very good agreement between the simulation and measurement results.
