Ultra wideband antenna

IEEE Communications Magazine, 2004
Ultra wideband antennas are specifically designed to transmit and/or receive very short time durations of electromagnetic energy. It is well known that UWB antenna design remains the major factor in the progress of UWB technology. This article describes a study of conventional antennas and why they are not suitable for a UWB system.

Ultra-wideband sources and antennas

Ultra- Wideband Short-Pulse Electromagnetics 4 (IEEE Cat. No.98EX112), 2002
Ultra-Wideband (UWB) sources and antennas are of interest for a variety of potential applications that range from transient radar systems to communications systems. In this paper, we discuss the research issues and progress being made in gas, oil and solid state switching, UWB sources, and antennas.

An ultra-wideband receiving antenna array

2013 IEEE International Symposium on Circuits and Systems (ISCAS2013), 2013
An UWB impulse radio receiving antenna array based on delay and sum beamforming is presented. The array is implemented using a simple impulse radio radar transceiver. The presented radar transceiver is fabricated in 90 nm TSMC technology, and it has a high speed sampler with sampling rate of 10 GHz which recovers the received signal with sufficient ...

Novel antennas for ultra‐wideband communications

Microwave and Optical Technology Letters, 2004
AbstractTwo novel antennas for UWB communications, both inspired from bowtie and triangular patch structures, are presented and tested. This paper proposes their study and optimization in order to cover the new WPAN standard and facilitate their integration on communication devices.
