In this paper, a compact fourth-order cascade quadruplet (CQ) passband filter (BPF) with improved selectivity is proposed based on the dual-metal-plane structure. To further improve the selectivity, more finite frequency transmission zeros (TZs) can be employed via introducing mixed electric/magnetic (EM) coupling in the cross-coupled arm between the nonadjacent resonators of the conventional CQ filter...
A compact dual-band bandpass filter (BPF) with improved stopband characteristics using stepped impedance resonators (SIRs) is presented. Multiple transmission zeros can be realized near the passbands of proposed filter by the cancelling effects of mixed electric and magnetic couplings. Dualband can be achieved by combining two sets of independent resonators with common input/output ports. A 2.4/5...
A compact third-order bandpass filter (BPF) with enhanced stopband characteristics is proposed in this paper. The filter consists of two stepped impedance resonators (SIRs) and a new resonator named closed loop SIR. The closed loop SIR which is embedded into the other two resonators for compact size is not the real structure of SIR, but it is similar to the conventional λ/4 SIR in some characters...

A compact bandpass filter (BPF) with enhanced stopband characteristics is presented in this paper. The proposed BPF consists of four improved stepped impedance resonators (SIRs),which implements into a box-section strcture. To improve the frequency selectivity and the stopband characteristics, additional transmission zero (TZ) was introduced by mixed electric and magnetic (EM) coupling. A new filter...
A compact dual-band bandpass filter with wide stopband based on stepped impedance resonators has been presented. The proposed filter consists of two quarter-wavelength modified SIRs which share a common grounded via-hole and two symmetrical open-end stubs. This structure without the open-end stubs can generate four transmission zeros (TZs) to achieve strong passband selectivity and the additional...
A new compact bandpass filter(BPF) with improved out-of-band performance is presented in this paper. The proposed BPF consists of two non-adjacent stepped impedance resonators (SIRs), which shared a common grounded via-hole. To improve the stopband characteristics, a π type capacitive circuit is introduced in the filter. The location of the transmission zeros can be controlled by adjusting the strength...
A compact fourth-order bandpass filter with good frequency selectivity is presented. The proposed BPF consists of four cascaded stepped impedance resonators (SIRs). Mixed electric/magnetic (E/M) coupling are introduced in the proposed filter to generate transmission zeros (TZs) near the passband for sharp frequency selectivity. The method on the generation of transmission zeros caused by mixed coupling...
