Abstract
experienced a blooming growth in the past few
years. The basic idea of this promising
technology is to directly transmit and receive
trains of extremely short baseband pulses that
spread over bandwidth of several GHz. It
features high-speed data rates, excellent
immunity to multipath interference, low power
consumption and reduced hardware complexity.
It can coexist with other radio systems without
causing harmful interference and gives the
possibility to ease the crowded frequency
spectrum in modern days. Generally speaking, it
is quite challenging to design an antenna to
simultaneously fulfill all the requirements in an
UWB system, including ultra-wide bandwidth,
omnidirectional patterns, constant gain and
group delay over the entire band, high radiation
efficiency and low profile. In this project, a
novel ultra-wideband antenna topology is
proposed and investigated. This new antenna
successfully combines the ultra-wideband
characteristics of the tapered slot antennas with
the unique features of the printed dipole
antennas, i.e. the omnidirectional patterns. The
parameter study is performed, and the antenna
performance is analyzed in both frequency as
well as time domains. In addition, the proposed
antenna will be suitable for other indoor wireless
communication systems as well as wideband
applications.
