Abstract :
An improved microstrip open-loop bandpass filter with controllable electric and magnetic mixed coupling is proposed. An additional transmission zero can be produced and precisely controlled by tuning electric and magnetic coupling parameters respectively. An equivalent circuit is used to analyze the behavior of the proposed filter. Simulated and measured results are in good agreement.
