The application of ultra-wideband (UWB) technology to low-cost short-range
communications presents unique challenges to the communications engineer. The impact of …

A new methodology is presented for characterizing an antenna system in both the time and
frequency domains with one set of parameters using a singularity expansion method …

This paper is a step toward defining the characteristics of a suitable antenna to exploit the
inherent advantages in pulsed communication systems, specifically that of ultra-wideband …

The geometrical and electrical features of the Vivaldi antenna are studied in the light of the
frequency-independent antenna theory. A scaling principle is derived for the exponential …

Impulse-based ultra-wideband (UWB) systems, notably unlicensed UWB systems operating
across or within 3.1–10.6 GHz, are unique systems possessing many desired …

An antipodal Vivaldi antenna for UWB applications is presented in this paper. The proposed
antenna is designed with simple structure but presents very good plot impedance …

Ultra wide band (UWB) has received a great amount of interest since the decision by the US
Federal Communications Commission (FCC) in February 2002 authorizing the emission of …

This paper introduces an improved shape of Antipodal Vivaldi Antenna from the normal
schematic structure which yields a high radiation gain. We have designed and fabricated the …

An antipodal Vivaldi antenna is presented for UWB applications. The proposed antenna with
elliptical microstrip-slotline transition and conducting arms shows acceptable UWB …

We present two novel ultra-wideband (UWB) antennas embedded in a low-temperature co-
fired ceramic (LTCC) package designed to house the UWB transceiver chip. Given their …
