Compact Microstrip Bandpass Filter With Two Transmission Zeros Using a Stub-Tapped Half-Wavelength Line Resonator
Lei Zhu, Senior Member, IEEE, and Wolfgang Menzel, Fellow, IEEE
Abstract―A compact microstrip bandpass filter is developed using a half-wavelength ( 2) transmission line resonator with a pair of tap-connected open-ended stubs. Such paired stubs with 2 constructs an equivalent line resonator. total length of about Together with two separated 4 line resonators, the three transmission poles can be achieved inside the passband. Meanwhile, two stub lengths are adjusted slightly longer and shorter than 4 to realize the two transmission zeros at both low and high rejection bands. Further, the long tapped
