MIMO ANTENNAS FOR MOBILE HANDSET AND TABLET APPLICATIONS.
PhDThe fast development of wireless communication technologies is pressing the antenna
engineers to investigate and design compact multiband antennas for the multiple-input
multiple-output (MIMO) systems, which is the key technology for the next generation
of mobile communications. The growing increase in the demand for transmitting and
exchanging large volume data, such as multimedia and interactive materials is
constantly fueling the need for higher data rates. MIMO systems have demonstrated
the capability to increase channel capacity, with a simultaneous increase in range and
reliability, without taking any additional bandwidth thus resulting in improved data
throughput. However, the performance of a MIMO system is highly dependent on the
nature of its propagation environment and the placement of antennas on device
platform. The true benefits of MIMO can be exploited through a smart design that can
adapt with changing system requirements or environmental conditions.
This research project has investigated the methods to make multiband MIMO and
multiband reconfigurable antennas on small mobile terminals with high
communication performance. This involves the methods for avoiding coupling
between multiple antennas and possible tuning of the antennas for next generation
mobile handsets. The aim of this work is to develop MIMO and reconfigurable
antennas for wireless terminals such as mobile handsets and tablets. The project is
divided in two phases with the first phase involving the development of multiband
MIMO antennas for handheld terminals and the second phase involves the design of
reconfigurable antenna for mobile handsets. Several prototypes of handset antennas,
capable of covering various cellular frequency bands, have been developed. The
research involves a substantial work on theoretical analysis, computer simulation and
experimental verification
