Suppression of Harmonic Passband of Bandpass Filters(BPFs) Using Parallel-Coupled Mushroom Structure [PDF]
The Journal of Korean Institute of Electromagnetic Engineering and Science, 2007 Harmonic band of bandpass filter(BPF) is suppressed using coupled mushroom structure. Between double positive (DPS) transmission line such as microstrip and double negative(DNG) transmission line such as one dimensional mushroom structure, strong coupling broadly arises in the cross range of dispersion curves of isolated microstrip and mushroom ...
