In this letter, a compact ultra-wideband (UWB) bandpass filter (BPF) with triple notched bands is presented. The basic UWB BPF is realized by feeding a modified multiple-mode resonator (MMR) properly with two aperture-backed interdigital coupled lines. The modified MMR can create five modes in band and two transmission zeros near the lower and upper cutoff frequencies, improving passband selectivity...
A compact ultra-wideband (UWB) bandpass filter (BPF) with triple sharply notched bands and sharp rejection shirts using spiral defected ground structure (DGS) is proposed. The filter comprises two aperture-backed interdigital coupled lines and a modified compact multiple-mode resonator (MMR) which is formed by a new triple-mode resonator and a stepped-impedance open-end stub in the centre. The modified...
Driver fatigue problem is one of the important factors of traffic accidents. Recent years, many research had investigated that using EEG signals can effectively detect driver's drowsiness level. However, real-time monitoring system is required to apply these fatigue level detection techniques in the practical application, especially in the real-road driving. Therefore, it required less channels, portable...
This letter presents a novel type of compact, low insertion loss (IL) planar microstrip filter, which is mainly composed of two hybrid resonators with a mixed electric/magnetic (EM) coupling between them. Tunable EM coupling is constructed to realize a tunable transmission zero (TZ) very close to the passband. And two folded T-shaped feed lines are adopted to introduce another tunable TZ and obtain...
