“…From what we saw in the above, the importance of semiellipse is widening the bandwidth, especially the part of the low frequencies. We can conclude that with the use of semiellipse in the bottom of the studied filter, the bandwidth has been extended from (4-11) GHz to (3)(4)(5)(6)(7)(8)(9)(10)(11) GHz and also, we notice that there is an improvement in the level of insertion loss…”

“…The length of the U-shaped resonators is (L5 +2L6) and it is about one-half wavelength of the central frequency (6.85 GHz) of the microstrip filter. As can be seen from Figure 3(b), the bandwidth has been improved as it has become extended from (3.5-10 GHz) to (3)(4)(5)(6)(7)(8)(9)(10)(11)(12). In addition, the appearance of three poles is observed in the passband.…”

“…There are many techniques presented to design UWB BPF like defected ground structure (DGS) [2,3], multiple-mode resonator (MMR) [4], modified split ring resonator (MSRR) [5], multilayer coupled structure [6] and surface-to-surface broadside coupled structures that have exhaustively been used in the design of UWB-BPFs [7][8][9] . The microstrip-to CPW-based UWB filters, compared with the rest, have minimum insertion loss response in the passband due to the tight broadside coupling of the structure [10]; these techniques have been widely used to achieve UWB characteristics.…”

This paper presents a new design of a super compact Ultra wideband (UWB) band-pass filter (BPF) with rejection of X-band satellite applications. For covering the UWB bandpass, the proposed filter is realized using hybrid technique which is achieved by using a Microstrip-Coplanar waveguide-Microstrip transition. The basic structure consists of a modified microstrip in the top layer and CPW in the bottom layer. Later, open-circuited stubs are embedded in the top to implement in-band transmission zeros (TZ) so as to circumvent interference. The simulated results show that the UWB bandpass filter has a high adaptation (S11 ≤ −18 dB) and insertion loss better than 0.4 dB at the passband. The impedance bandwidths are about 114% (3–11 GHz) with upper stopband extends to more than 14 GHz with a depth of greater than 38 dB. In addition, the UWB BPF shows a flat group delay performance with a variation of about 0.15 ns over the entire bandwidth. A prototype of the filter is fabricated and tested. Good agreement is achieved between measurement and simulation. The proposed UWB BPF is compact in size with overall dimensions of 14 by 9.2 mm2. Consequently, the obtained results prove that the presented filter is suitable for UWB wireless devices.

-In this Paper, a simple wideband BPF is proposed using a slot resonator which produces passband of 7-16 GHz. The transmission characteristics are improved by etching a square slot resonator in the half mode SIW BPF. The proposed filter uses a microstrip transition which results in better return loss performance and wider bandwidth. A novel compact bandpass filter is designed and simulated using ADS software. Keywords-bandpass filter, wider bandwidth, pass band. transmission line is W1 and the length of the SIW I. INTRODUCTIONHigh data rates, low power transmissions, excellent range resolution are main advantages of Ultra Wideband (UWB) technology [1]. UWB filters have lower insertion loss, good return loss performance, good selectivity and better rejection performance. A new design of wideband microwave bandpass filter is constructed by combining S-shaped slot and L-shaped slot loaded quarter-mode substrate integrated waveguide filter [2]. A bandpass filter with a 1.39 GHz bandwidth centered at 4.54 GHz is proposed by using CMRC resonators [4]. Good return loss performance and sharp selectivity are produced using two stubs in a bandpass filter for UWB applications [5]. Microstrip stopband bandpass filters are proposed using two shapes of split ring resonator (SRR) [6].
