Abstract :
A new topology of narrowband band-pass filter based on modification of classical tapped-line interdigital coupled lines filters is presented. From a sensitivity point of view, this new topology appears as very attractive when designing very narrowband filters. Theoretical and experimental results in coplanar technology are presented. The theoretical study is carried out by both a circuit modelling approach (HP-MDS) and a full wave analysis (Agilent-Momentum).
