Abstract:
Aim of this contribution is to study the
impact of typical ultra-wideband (UWB) antennas for
communications over a spatial wireless channel. In order
to adequately consider the directivity properties of real
antennas, our analysis is suitably based on a ray tracing
UWB channel model since this reflects the dependence
on the Angle of Arrival (AoA) and Angle of Departure
(AoD) of any multipath. A mathematical framework is
given which also allows an optimization of such an UWB
Multiple Input Multiple Output (MIMO) system using
different types of transmitting and receiving antennas on
behalf of idealistic omnidirectional ones. Beside the angle
dependence, the antenna transfer functions are without
doubt frequency dependent on such a large UWB bandwidth,
so that they will be evaluated with suitable analog
design specialized tools for the fast and accurate threedimensional
electromagnetic simulation of high frequency
circuits. Simulation results allowing concrete guidelines on
the antenna influence will be provided in the last section
of this paper.
