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...

This paper presents the design of a compact integrated UWB-UHF RFID solution enabling simultaneous wireless data and power transfer. The described integrated dual-band antenna is designed to cover the lower European UWB 3.1 to 4.8 GHz band for communication and localization functions and the European UHF RFID 868 MHz band for RF Energy Harvesting. Simultaneous operations are guaranteed by means...

Ultra wideband (UWB) radar is considered a promising technology to complement existing camera-based surveillance systems because, unlike cameras, it provides excellent range resolution. Many of the UWB radar imaging algorithms are based on large-scale antenna arrays that are not necessarily practical because of their complexity and high cost. To resolve this issue, we previously developed a two...

In this paper, a mounting method is proposed for antennas used in ultra wideband (UWB) body area network (BAN) channel sounding, which reduces the antenna’s electromagnetic coupling to the human body. Coupling with the body is shown to distort the free space characteristics of the antenna. An antenna mount modification is proposed to reduce this distortion, and decrease the variation in antenna...

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 ante...

The need for development of microstrip patch antennas for ultra-wideband (UWB) communications has been very well recognized.UWB antennas are mainly used for wearable MIMO sytems,weather mesurements and also UWB radar applications. Patch antenna can be a good choice for handheld devices in UWB applications.There was a great success in finding a suitable structure for mobile applications.This pap...

An ultra wideband impulse radio (UWB-IR) system can be extremely distorted through a channel even for free-space transmission because of antenna dispersion. This highly degrades the link budget performance. Therefore, the understand of antenna characteristics, which effects on waveform distortion, is necessary. This paper studies the waveform distortion due to antenna on free space transmission...

In this paper, subject-specific narrowband (2.45 GHz) and ultra-wideband (3–10.6 GHz) on-body radio propagation studies in wireless body area networks (WBANs) were performed by characterizing the path loss for eight different human subjects of different shapes and sizes. The body shapes and sizes of the test subjects used in this study are characterised as thin, medium build, fatty, shorter, av...

Low-complexity rapid timing acquisition constitutes a major challenge in realizing the high potential that ultra-wideband (UWB) wireless technology promises for indoor communications. We derive and test two such timing acquisition algorithms which capitalize on the cyclostationarity that is naturally present in UWB transmissions. Our novel schemes are blind, they do not require multiple antenna...
