Abstract :
In this article, a wideband bandpass filter (BPF) using half-wavelength resonator tapped in the middle with loaded stub is presented. The proposed filter has 3-dB fractional bandwidth (FBW) of 75% with a very sharp cutoff due to two transmission zeros at lower and upper stop-bands. It has low passband insertion-loss with good return-loss characteristics.
