Abstract :
A new class of compact microstrip filter loaded with a low-characteristic impedance triangular stub is introduced. The respective filter upper stopband selectivity is improved. Without the presence of cross-coupling between non-adjacent resonators, one transmission zero is observed. Frequency tuning can easily be achieved by adjusting the reactance of the stub
