Abstract :
Proposes a novel folded skill and a simpler method than that of older methods. The advantages of this new structure reveals a better skirt factor than that of the conventional folded /spl lambda//4 series open stub, and it reduces the folded area of the conventional structure by at least 50%. Besides, by using the new folded /spl lambda//4 open stub to realize a bandpass filter, the size of the circuit will be reduced greatly and achieve better stopband rejection.
