Abstract: A compact high‐selectivity tunable dual‐mode microstrip bandpass filter (BPF) with constant bandwidth is proposed in this letter. Three self‐adaptive transmission zeros (TZs) are generated due to the frequency‐dependent source‐load (S‐L) coupling and intrinsic characteristic of… read more here.
