摘要: A new dual-mode differential bandpass filter on a squared microstrip ring resonator with slotline feeding scheme is presented. This consists of resonator, four identical slotlines equally spaced along the and two differential-mode line to transitions. By perpendicularly installing between coupling strength them can be dramatically increased as desired. More importantly, only modes propagate slotline, so proposed naturally block common (CMs) from propagation achieve good CM suppression. To verify design concept, has been designed fabricated. Good agreement simulated measured results attained.
