This paper proposes a simple and effective method to designing wide-stopband bandpass
filters and diplexers using uniform impedance resonators. Microstrip terminated parallel …

A procedure for improving the stopband response of planar bandpass filters is presented in
this letter. The technique is based on the introduction of transmission zeros by using lumped …

The design of planar sharp-rejection low-pass and bandpass filters (LPFs and BPFs)
featuring a very broad stopband is addressed in this paper. For the LPF case, two new …

In this letter, a fully packaged dual-mode bandpass filter (BPF) with wide upper stopband is
presented. The stripline patch resonator loaded by the shorting slabs is adopted to achieve …

In this paper, a wideband bandpass filter with composite series and shunt resonators is
proposed together with a direct synthesis and design theory. The filter configuration can …

Existing and newly adapted techniques for suppressing harmonic responses in microstrip
filters were combined. Stagger tuning using additional stubs to shift the resonances has …

This paper proposes a new coupling matrix synthesis technique called the coupling matrix
compression technique, which focuses on reducing the dimension of the N+ 2 coupling …

This paper gives a complete theoretical study in a narrow band for the parallel-coupled
filters based on short-circuited stub-loaded resonators. It describes a synthesis method for …

This paper proposes a miniature microwave bandpass filter. It comprises quasi-lumped
suspended substrate stripline resonators of a new type. Their common substrate consists of …

The stopbands of microstrip filters were extended by additional stubs to alter the resonant
frequencies of the 2nd and 3rd harmonics, making the resonators stagger tuned. The stubs …
