Abstract :
A configuration for the realisation of extracted pole planar elliptic function filters is proposed. The new filter configuration consists of chamfered patches in a microstrip assembly which are coupled by a slot. The two degenerated modes that can exist in a two-dimensional square resonator are slightly shifted in resonance frequency
