“…In recent years, many filters have been developed in various ways. For example, using multiple-mode resonators (MMR) [2][3][4][5][6], using stub-loaded structures [7], using cascaded structures [8][9][10], and using composite right/left-handed structures [11]. In a previous work [12], a UWB filter is developed by using a pair of coupled lines and two open stubs.…”

Abstract-In this article, a compact ultra-wideband (UWB) band-pass filter (BPF) with wide upper stopband is presented. The filter is designed with a UWB response from 3.2 GHz to 10.8 GHz with low insertion loss of 0.9 dB and less than 0.19 dB at the center frequency (6.67 GHz). The filter is also designed with a broad upper stopband with high rejection level of 20 dB. The group delay is flat with maximum of 0.4 ns. The proposed UWB filter is constructed by using a pair of parallel coupled lines and two ring resonators. In this design, the ring resonators provide two new excited modes to widen the desired UWB passband and also create two tunable transmission zeros to achieve a wide stopband. Good agreement is observed between simulated and measured performances of the UWB filter.

“…These systems need to be compact and integrated with high performing devices to reduce cost and enhance performance. Thus, it requires wideband antennas for high-speed transmission and simple hardware configuration relative to conventional wireless communication systems [7–10]. UWB (ultrawideband) system is regarded as a promising technology due to its allocation of the 3.1–10.6 GHz bandwidth by the Federal Communications Commission (FCC) [7].…”

In this paper, a new compact wideband monopole antenna is presented for wireless communication applications. This antenna comprises of a new radiating patch, a new arc-shaped strip, microstrip feed line, and a notched ground plane. The proposed radiating patch is combined with a rectangular and semi-circular patch and is integrated with a partial ground plane to provide a wide impedance bandwidth. The new arc-shaped strip between the radiating patch and microstrip feed line creates an extra surface on the patch, which helps further widen the bandwidth. Inserting one step notch on the ground plane further enhances the bandwidth. The antenna has a compact size of 16×20×1.6mm3. The measured result indicated that the antenna achieves a 127% bandwidth at VSWR≤2, ranging from 4.9GHz to 22.1GHz. Stable radiation patterns with acceptable gain are achieved. Also, a measured bandwidth of 107.7% at VSWR≤1.5 (5.1-17GHz) is obtained, which is suitable for UWB outdoor propagation. This antenna is compatible with a good number of wireless standards, including UWB band, Wimax 5.4 GHz band, MVDDS (12.2–12.7GHz), and close range radar and satellite communication in the X-band (8-12GHz), and Ku band (12-18GHz).

Abstract-A novel compact tri-band band-pass filter (BPF) with transversal signal interaction concepts, based on composite right/left-handed transmission lines (CRLH-TLs) resonator and parallel stepped impedance resonator (SIR), is presented. The main path is based on a dual-mode CRLH-TL resonator, which exhibits the first two passbands. The secondary path is a SIR, which contributes to the third passband and generates another transmission zero between the first and second passbands simultaneously. The proposed filter has been simulated, fabricated and measured. Both the simulated and measured results show that the filter has a high selectivity with a compact size as small as 0.18λg × 0.12λg.
