Abstract :
A new type of enhanced coupling structure of microstrip ring resonator with two coupled lines and a slit is suggested. The insertion and return losses are shown to be improved compared with those of conventional line-to-ring resonator. Also, it has an intensive suppression above the third harmonic which is very useful for its application to microwave circuits.
