Consumer demand for multimedia and wireless applications is growing at a rapid rate. Furthermore, consumers are expecting automobiles, especially luxury vehicles, to be enabled with the latest consumer multimedia and wireless products. These in turn call for antenna systems to be integrated into automotive vehicles in a manner that is acceptable to automotive consumers.

The purpose of this thesis is to provide an overview on the application of smart antennas to mobile communications by devising a new type of Ground Plane with Rings (GPR) that can enhance performance of low-profile antennas. Investigating and analysing the effects of vertical monopole antenna on a Ground Plane with Rings (GPR) compared to a conventional continuous ground plane will be conducted and studied. Simulations are carried out using CAD (Computer Aided Design) software package known as FEKO.

It is proposed that the behaviour of this structure (GPR)will lead to a reduction in pattern sidelobes resulting in improvements in radiation pattern front-to-back ratio and overall antenna efficiency. Thus this unique material can serve as the ground plane for new kinds of low-profile antennas.
