“…The frequency range of operation for such antennas is generally defined as 3.1 GHz to 10.6 GHz (the Federal Communications Commission (FCC) bandwidth). The operational bandwidth of an antenna is usually defined as the frequency range over which the return loss S 11 is less than 10% (-10dB) [6][7][8][9][10], although some papers present results in terms of VSWR. In this work we have modeled an existing design [11] using ADS, analyzing the results in terms of S 11 and then optimized the design stage-by-stage to improve the bandwidth performance whilst reducing the overall patch size relative to the original design.…”

The paper presents a co-planar wave guide (CPW)fed slot loaded low return loss planar printed antenna with a small size designed for wireless communication and UWB applications. First, a conventional UWB antenna is modeled to provide a reference point for the modeling and then the shape is modified by a self inverted configuration to achieve higher bandwidth and size reduction. To improve the gain and efficiency, a combination of corner features and loading slots are introduced. The primary aim throughout the modeling was to achieve the minimum possible value of return loss (S 11 ) below -10 dB over the FCC-defined UWB frequency range. The antenna was designed, simulated and modified using Agilent's Advanced Design System (ADS). It was fabricated on FR4 substrate and measured return loss results are presented.

“…Conversely, UWB transmission devices do not need to transmit a high-power signal to the receiver and can have a longer battery life or be smaller to reduce the wearable devices size [4][5][6][7][8][9][10][11]. Several antennas have been developed for wearable antennas in the form of flexible metal patches on textile substrates [11][12][13][14][15].…”

Abstract-Communication technology is increasingly pervading everyday life. The rapid progress in wireless communication besides the increasing interest in wearable antennas and electronics in civil, medical, sport wear and military domains promises to replace wiredcommunication networks in the near future in which antennas are in more important role. Recently, there has been growing interest in the antenna community to merge between wearable systems technology, Ultra-Wideband (UWB) technology and textile technology. All these together have resulted in demand for flexible fabric antennas, which can be easily attached to a piece of clothing. In this paper, three different structures of UWB antennas using clothing materials and suitable for wearable application were fabricated and presented. The substrate of the designed antennas was made from jeans textile material, while radiating element and ground plane are made out of copper tape. The operating frequency of all three designs is between 3 GHz and 12 GHz. Measured results are compared with simulations and good agreement was observed.

“…However, one limiting factor of these antennas is their low bandwidth. Therefore, several configurations were carried out to increase the bandwidth of planar antennas such as ultra-wideband antennas rectangle shape [1][2][3][4], circular [5][6][7][8], elliptical [9], triangle [10] and several other types of antennas [11][12][13][14][15][16][17].…”
