A novel slot-shaped defected ground structure (DGS) on the microstrip line to provide a band-rejection property with an improved Q factor is proposed in this paper. It has a size of only 11% of conventional dumbbell DGS unit section and 26.8% of U sharp DGS unit section, while the Q factor is 7.6 times than dumbbell DGS and 3.2 times than U-sharp DGS at the(More)
A novel patch-shaped patch loaded slotline (PLS) to provide a band-rejection property with an improved Q factor is proposed in this paper. It has size of only 28% of conventional dumbbell PLS unit section and 72% of the conventional open-loop PLS unit section, while the Q factor is more than 10.5 times than dumbbell PLS and 3.3 times than the conventional(More)
A kind of novel compact wideband bandpass filter (BPF) is investigated in this paper. It is composed of four open-circuited stubs, in which two of them are folded to minimize the whole size of the filter. The new filter has been simulated and the characteristics are analyzed. The calculated results show that the BPF has a wide 3 dB fractional bandwidth(More)
The aim of this study was to investigate the role of P-glycoprotein (P-gp) in the intestinal absorption of triptolide. In this research, the bidirectional transport of triptolide across Caco-2 cells was studied in vitro. Moreover, the pharmacokinetic profiles of orally administered triptolide with and without pretreatment with verapamil were determined in(More)
On the basis of coupledline sections and impedance steps as inverter circuits, novel wideband and compact filters are presents. The compact broadband microstrip filter using a folded multiple-mode resonator contains only one resonator, which operates as not only a resonant element, but also an open stub. In addition, the filter owns a compact size, a broad(More)
