This paper presents the harmonic cancellation of a 3rd order Butterworth response parallel-coupled bandpass filter by introducing periodical grooves. The cancellation was obtained by aligning the transmission zero of the tight coupling (TCg) coupler with the harmonic of the weak coupling (WCg) coupl...
