“…A tremendous interest in the exploration of UWB bandpass filters (BPFs) with good in-band transmission and out-of-band rejection performances has been aroused. Recently, various new structures and design methods have been used to develop new UWB bandpass filters, such as composite lowpass-highpass filter topology [1], coupled-line structure [2], planar balun [3], cross coupling structure [4], transversal signal-interaction [5] and multiple-mode resonators (MMRs) [6,7,8,9,10,11,12,13]. The multiple-mode resonator was originally used to design the UWB filter in [7].…”

A novel compact microstrip ultra-wideband (UWB) bandpass filter (BPF) is proposed using a multiple-mode resonator (MMR), aiming at transmitting signals in the whole UWB passband. The resonant frequencies of this MMR in the design are properly adjusted equally within the UWB passband. Then, two aperture-backed interdigital coupled-lines at the two sides are introduced for an effective enhancement of the capacitive coupling factor. Transmission zeros can be created at the lower and upper passband edges to improve the passband selectivity greatly. Finally, a microstrip UWB filter with good in-band filtering performance and sharp rejection skirts is simulated and fabricated with good agreement.

“…However, the existing wireless networks such as 5.8 GHz WLAN signals and some 8.0 GHz satellite communication systems signals can interfere with UWB systems, thus compact UWB BPFs with multiple notched bands are emergently required to reject these interfering signals [11][12][13][14][15][16][17][18][19][20][21]. To achieve a notched band, a pair of radial impedance resonators are used in [11], and a stepped impedance resonator is employed in [12,13].…”

Abstract-A new microstrip ultra-wideband (UWB) bandpass filter (BPF) with dual sharply rejected notched bands based on E-shaped resonator is proposed in this paper. The basic UWB BPF is designed using two microstrip interdigital coupled lines and one rectangular patch multiple-mode resonator (MMR). Then, to achieve dual band-notched performance, the proposed dual-mode E-shaped resonator is investigated and coupled to the rectangular patch multiple-mode resonator of the basic UWB BPF. To validate the design theory, a microstrip UWB BPF with two notch-bands centered at the frequencies of 5.8 GHz and 8.0 GHz, respectively, is designed and fabricated. Both simulation and experimental results are provided with good agreement.

“…The frequency spectrum adopted for UWB communication system in this letter, i.e., 3.1-10.6 GHz, follows the one authorized by the Federal Communications Commission (FCC) for short range and high speed wireless communications [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. In [1], a compact UWB BPF was presented based on shorted stubs and defected ground structure (DGS) with dual notched bands while a multimode resonator (MMR) was used for UWB BPF as shown in [2].…”

“…Asymmetric feed structures were introduced in [9,10] for notched-bands applications. In [11][12][13], short line, radial stub, and embedded stepped impedance resonator (SIR) were used to create a notched band for avoiding signal interference. Compact UWB BPFs with dual-, triple-, and quad-notched bands were presented in [14,15].…”

Abstract-A novel ultra-wideband (UWB) bandpass filter (BPF) with notched band based on microstrip/slotline ring resonators is presented in this paper. The UWB BPF is fabricated with two microstrip ring resonators on the top copper layer and a slotline ring resonator on the bottom ground layer. Thus, an ultra-wide passband can be achieved owing to the coupling effects and microstrip/slotline transitions of these three ring resonators. Then, a notched band which is created at 8.0 GHz for satellite communication system is designed based on loaded short-circuited stubs. Both the simulated and measured results show that this compact UWB BPF has good performances of wide passband and notched band.
