Abstract
A configuration for the realisation of canonical microstrip elliptic function narrow-band bandpass filters is proposed. The new filter configuration consists of two identical arrays of microstrip square open-loop resonators. The two resonator arrays are proximately placed on the same plane so as to allow nonadjacent electric and magnetic couplings to be realised and ajusted. A theoretical investigation has confirmed the feasibility.Keywords
