“…Therefore, many researchers provide a large number of solutions. These solutions mainly include: (a) ultrawideband omnidirectional antenna, of which wafer monopole antenna and various special‐shaped‐pole antennas , are mainly used in the frequency band from 3.1 to 10.6 GHz (approved by FCC). But generally, these kinds of antennas are omnidirectional antennas with low gain, which could be arranged as an array to improve the gain, however, the feed network of the array is too difficult to solve; (b) wide slot antennas ; (c) antennas with resistance gradual changing structure, including some ultrawideband directional antennas, such as Vivaldi antenna, TEM horn antenna .…”

A compact six pairs of printed log‐periodic fractal dipole antenna (FLPDA) is proposed in this article for wireless applications. These applications are terrestrial digital video broadcast‐T band (470–862 MHz), 3.5WiMAX band (3300–3800 MHz), and the WLAN (wireless local area network) IEEE 802.11b, g frequency bands. The impedance bandwidth (|S11| < −6 dB) of the proposed antenna is extended from 0.5 to 10 GHz with an average gain of 5.5 dBi. The fractal LPD antenna is simulated and designed with the software high frequency structure simulator. Both numerical and experimental results show that the FLPDA antenna has stable directional radiation patterns and apparently miniaturized effect, which are suitable for various ultrawideband applications. The results show that the antenna achieves the necessary lateral size reduction of 45% of the normal log‐periodic antenna while keeping its radiation characteristics nearly constant. © 2014 Wiley Periodicals, Inc.

“…Therefore, UWB provides dramatic channel capacity at short range that limits interference. Equivalent circuit models [2] of microstrip discontinuities are widely used to enhance the speed of microwave circuit designs [3]. The equivalent circuit parameters can be determined directly from hardware experiments or from curve-fitted formulas [4], or extracted from software results.…”

“…The commercial use of the frequency band 3.1 to 10.6 GHz for radar, positioning and data transmission has been released by the Federal Communication Commission (FCC) in 2002 [1].UWB antennas have enormous attention in both academia and industry for applications in wireless transmission systems [2]. Impulse-Ultra wideband (I-UWB) is a carrier less short range communications technology in which its transmission occupies a bandwidth of more than 20% of its center frequency (>500 MHz) [3].Wireless communication systems have developed rapidly in recent years, an antenna as a front component is required to have a wide band, good radiation performances and sometimes switchable ability [4].…”

In this paper, a patch antenna with band notched characteristics for ultra wide band is proposed. The proposed antenna design is simulated on electromagnetic (EM) simulation software using FR-4 substrate with dielectric constant of 4.4 and thickness of 1.6 mm.The proposed antenna has a compact structure, the total size is 15×14.5 mm 2 and fed with 50 microstrip by optimizing the width of partial ground, the width of the feed line to operate in UWB.With the design, the return loss is lower than 10 dB in 3.1-10.6 GHz frequency range and show the band-notch characteristic in the UWB band to avoid interferences, which is caused by WLAN (5.15-5.825 GHz) and WiMAX (5.25-5.85 GHz) systems. In addition, band-notched filtering properties in the 5.15-5.825 GHz are achieved by rectangular slot on the radiating element.The proposed antenna is easy to integrate with microwave circuitry for low manufacturing cost. The antenna structure is flat, and its design is simple and straightforward.
