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), 2002Ultra-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), 2013An 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, 2004AbstractTwo 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.

Design of a directive ultra-wideband antenna
2nd European Conference on Antennas and Propagation (EuCAP 2007), 2007This work presents a novel directive Ultra-Wideband (UWB) antenna. The antenna shows an average gain of 7 dB over the band of interest (i.e., 4-10 GHz) with a return loss better than -10 dB. A broadband balun is also included in the realization. The antenna transfer function has been measured and the effect on pulse transmission has been evaluated ...
