“…Ultrawideband (UWB) technology has risen dramatically since Federal Communications Commission authorized the frequency band of 3.1–10.6 GHz for commercial purposes. In recent years, UWB bandpass filters (BPFs), as one of the essential components in UWB systems, have been designed based on different methods and structures: multiple‐mode resonator ; cascaded broadside‐coupling . However, to avoid the existing Wireless Local Area Network signal, a notched band is necessary within the passband of the UWB BPF.…”

A super compact ultrawideband (UWB) bandpass filter (BPF) with one narrow notched band and wide stopband is presented. The basic UWB BPF contains four folded shunt quarter‐wavelength short‐circuited stubs separated by a three‐line coupled structure with length of λg0/4. A coupled folded quarter‐wavelength resonator and three semicircle defected ground structures are used to achieve one desired notched band and good stopband characteristic, respectively. The predicted results on S‐parameters are compared with measured ones and good agreement is achieved. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:763–765, 2015

This paper proposes a compact size design of wideband bandpass filter (BPF). The broad-side coupling microstrip-slot technique is used to accomplish a good passband response with very low insertion IntroductionThe immense needs in the direction of high-speed wireless communication connection appear to be never end, despite the current facilitation of the fourth generation (4G) of the wireless communication system. Where, the technology of wireless communication actuates toward fifth generation (5G) with the concept of communication that not restricted to humans but additionally the machine-to-machine and vehicle-to-vehicle, which anticipated by the year 2020. This intense 24/7 desire of the ubiquitous and limitless high-speed communication access to any apparatus at anytime pilots to excessive challenge and problem to the engineers and researchers implying network planning, and radio frequency (RF) and microwave component design. Subsequently, the vital front-end component features in the wireless communication system, includes bandpass filter (BPF). In recent years, it can be seen that various rapid developments in the variety of BPF designs have been reported in the literature [1][2][3][4][5][6][7].In [1], the authors present a theory and direct synthesis of a wideband progressively coupled BPF. The designed filter is claimed adequate to accomplish similar manageable number transmission zeros as that of resonators over the passband. The resonators contain a parallel pair attached capacitive loaded, and grounded inductive stubs are linked over a short section of a transmission line with a certain assigned electrical length, which allow the filter to have a wide range of stopband.Besides, numbers of researchers have also proposed a design of bandpass filter by using defected ground structure (DGS) technique [2][3]. In [2], the design has four coupled Ushaped DGS on the common ground plane. Meanwhile, at the top of the designed filter, shunt coupled T-shaped microstrip lines is added in order to act as an inverter for the filter. As a result, the BPF displays two transmission zeros on either side of the passband, thereby improving the selectivity of the filter on both sides of the passband. Similar to the filter reviewed in [3], the DGS has been implemented into the filter designed whereas the motivation of the DGS technique is impending from the bandgap structures of electromagnetic/photonic (EBG/PBG). In the paper, the authors introduce the function of metamaterials. Metamaterials are employed in order to accomplish a variety of performance-enhancement features. The authors have claimed that the filter design with DGS and metamaterials to be simpler compared to the complex EBGs/PBGs.

A compact ultra‐wideband (UWB) band‐pass filter (BPF) with dual narrow notch‐bands based on a dual‐mode stepped impedance resonator (SIR) is presented.The proposed UWB filter employed broadside‐coupled microstrip ring‐coplanar waveguide structure. Two notch bands are obtained by introducing one coupled dual‐mode SIR with metalized via hole to ground. Theoretical and simulated results are presented, which are in good agreement with the measured results. © 2012 Wiley Periodicals, Inc.
