摘要: Resonant processes in dual-mode microstrip square-ring band-pass filter fed through L-shaped coupling arms have been studied using the Finite Difference Time Domain (FDTD) simulations. The performed field analysis has revealed that act as additional half-wavelength resonators coupled with ring both electric and magnetic fields. New designs horseshoe instead of developed, which provide either pure or at resonant frequency. obtained results demonstrate possibility to essentially improve characteristics. Simulations verified by measurements fabricated prototypes.
