Abstract
A simple quarter-wavelength bandpass filter (BPF) with wide stopband is proposed. The harmonic suppression is achieved by discriminating coupling. Using an appropriate coupling region, coupling coefficient at the third harmonic is almost zero whereas that in the passband can be tuned to the desired value. An example filter is designed, manufactured and tested. The measurements show 20-dB rejection level from 1.16 0 to 6 0. It confirms the feasibility of the method. © 2011 Engineers Australia.
