Ultra wideband (UWB) technology based primarily on the impulse radio paradigm has a huge potential for revolutionizing the world of digital communications especially wireless communications. UWB provides the integrated capabilities of data communications, advanced radar and precision tracking, location, imperceptibility and low power operation. It is therefore ideally suited for the development...

A novel compact-sized ultra-wideband (UWB) bandpass filter (BPF) is proposed in this paper. The proposed BPF is highly selective and is able to eliminate WLAN signals from 5.15-5.35 GHz, and downlink of X-band satellite communication signals from 7.25-7.75 GHz. Generally, a multiple-mode resonator (MMR), comprised of a U-shaped line, with two high impedance stubs connected to it, and one steppe...

A novel monopole-type antenna, which covers the bandwidth 3.1 10.6 GHz is presented. The shorted and folded planar monopole antenna is constructed by folding a thin copper sheet in such a way that one edge of the radiating element is connected to the ground plane. Simulated and measured results show suitable characteristics for communications systems using ultrawide-band (UWB) technology. Moreo...

Ultra-wideband (UWB) technique has become one of the most fascinating technologies with various antennas. It has the merits of high speed transmission rate, low power consumption and simple hardware configuration over conventional wireless communication systems. The research and development of the UWB systems including antennas have been widely performed [1-5]. Recently, UWB systems have focuse...

The design and performance of a band pass filter for UWB communications is presented in this paper. Open loop resonators consisting of parallel arms (stubs) protruding from a 50Ω transmission line create the required rejection bands. The arms height, width and spacing control the bandwidth achieved by the filter. Each pair of arm creates one reject band in the transmission response. Three filte...

Abstract—In this paper, a planar monopole antenna for UltraWideband (UWB) communications with a notched behavior in the two sub-bands UNII1 and UNII2 of the Wireless Local Area Network (WLAN) band is presented. The antenna geometry is described by means of a spline curve and a rectangular slot. Numerical and experimental results are reported to assess the effectiveness of the proposed design in...

The increasing needs of free licensed frequency bands like Industrial, Scientific, and Medical (ISM), Wireless Local Area Network (WLAN), 5G for underwater communications required more bandwidth (BW) with higher data transferring rate. Microwaves produce a rate data, their associated devices are smaller in comparison sonar ultrasonic. Thus, transceivers should have broad BW to cover band, espec...

Time Hopping Ultra Wide Band (TH UWB) commonly encodes the data symbols by shifting the position of the transmitted pulses by a quantity that is quantized over the inter-pulse interval range. In this paper, we relax the hypothesis of a discrete value for the time shift introduced by the TH code, by considering the possibility of generating real-valued codes that introduce time hopping in a flui...

this paper presents an e-ring shaped printed monopole antenna for uwb applications with dual notched bands performance. in order to generate single frequency band notch function, we applied a u-ring shaped monopole antenna, and by inserting a rectangular ring in the centre of it an e-ring shaped radiating patch created and a dual band-notch function can be achieved. the measured bandwidth of th...
