Antenna Project .An antenna for a wireless sensor network for trains is designed and built. The network will monitor temperature and vibrations of the wheel bearings on the train wagons.
A wide variety of space diversity techniques have been proposed and the development of a low cost adaptive antenna array is crucial in the realisation and implementation of these systems. Results of a comparative study between adaptive antennas and various diversity techniques are presented. Regarding the propagation models it is fair to say that there have been a great deal of ongoing research in this area. It is also fair to conclude that much of the available information need improvements particularly in two areas. This includes the desire to develop physics-based deterministic models that take into account unique propagation environments.
