“…On February 14, 2002, an unlicensed band called UWB from 3.1 to 10.6 GHz with a span of 7.5 GHz was declared by the Federal Communication Commission (FCC) for commercial applications [3]. Microstrip or planar antennas are highly recommended for UWB technology because of their undisputed advantages over other antennas and so forth [4].…”

A CPW-fed ultra-wideband (UWB) monopole antenna design which exhibits triple band stop functions is demonstrated. The proposed antenna comprises a Split Ring Resonator (SRR) and inverted U slots on a metallic patch to exhibit triple band-notch functions for WiMAX (3.3-3.6 GHz), Cband (3.8-4.2 GHz) and WLAN (5.1-5.8 GHz) bands. The slot width optimization is examined to tune the band-notch resonance frequency, and their effects are exhibited by surface current distributions. The antenna has compact size of 26 * 30 mm 2 , and it functions over 3 to 11 GHz with VSWR < 2 except notched bands. The SRR loaded dual band-notched antenna and amended inverted U slot integrated antenna both are fabricated and their VSWR, radiation characteristics measured. The antenna demonstrates excellent agreement between measured and calculated results.

“…By April of that year, the FCC gave formal approval for the unlicensed use of the technology between 3.1 and 10.6 GHz [1]. Since then, UWB technology has been widely focused, and as an essential part of UWB systems, research on UWB antenna has become a highly attractive topic in both academic and industry communities of telecommunication [2,3].…”

“…With the rapidly growing demands for more diverse broadband services, a flexible data-optimized access network infrastructure is required to alleviate the rising traffic load [1][2][3]. The wavelength-division multiplexing (WDM) technology allows tens of wavelength channels to be delivered simultaneously over a single-mode fiber in a transparent fashion, which enables a tremendous increase in the transmission capacity of an optical communication network.…”

In this article, we propose a low-power (2.76 mW) CG LNA for UWB systems. This new matching network consists of a series L S1 -R S1 in series with a parallel L S2 -R S2 to enhance the input matching bandwidth. As demonstrated, flat and high S 21 as well as flat and low NF performances could be achieved by suitably choosing the values of the connecting inductor L C and the peaking inductor L D2 . The state-of-the-art results (P D of 2.76 mW and FOM of 4.3) of the proposed wideband CG LNA indicates that it serves well for 3-to 10-GHz UWB or even higher frequency wideband communication system applications.

“…The arms of antenna are connected by a shorting bridge for reduction of arm length and increases in maximum gain at the higher frequencies for a consistent gain response over the achieved bandwidth. The enhancement of gain and gain stability is conducive to pulse-based UWB systems as an UWB antenna may function as a bandpass filter and distort the waveforms of radiated/received pulses [2], [17]. The performance of the proposed antenna is examined in both frequency and time domains.…”

A planar dipole antenna is proposed with enhanced impedance and gain performance across an ultrawideband (UWB) operating bandwidth of 3.1-10.6 GHz. The proposed antenna consists of two semi-elliptical-ended arms connected by a shorting bridge. With the shorting bridge, the length of the antenna is reduced and the radiation performance in terms of gain is improved especially at higher frequencies. The performance of the proposed antenna is validated experimentally using a wideband balun to realize the microstrip-co-planar strip transition. The results show that the proposed antenna can achieve a gain of 2.4-6.2 dBi across a VSWR = 2 impedance bandwidth of 118% (2.8-10.9 GHz).The time domain responses of pulsed UWB signals through conventional and proposed antennas are compared. Furthermore, a parametric study is performed to provide antenna engineers with the information about the design.
