| description |
Nowadays achievements on mobile satellite system (MSS) communication give a
great concern for research in global wireless communication fields. This has prompted
the development of several Non Geostationary Earth Orbit (Non-GEO) satellite systems
that promises worldwide connectivity for real-time communications. The mobility of
Non-GEO satellite systems require a high directivity satellite tracking technique and a
reliable inter satellite handover algorithm to ensure that connectivity between two end
users are not interrupted as a result of satellite movement.
In this thesis, phased array antenna has been proposed to obtain high directivity
beam for satellite tracking. In order to do this, the phased array antenna mathematical
model has been developed. This mathematical model has demonstrated that a narrow
beam with high directivity could be generated. By changing the phase of the exciting
currents in each element of antenna array, the radiation pattern could be varied through
space. Thus, the generation of multiple and steerable beams also could be depicted by
varying the phase shift of phase shifter with appropriate spacing between each elements to be sufficiently large. It is also shown here that the generated radiation beamwidth can
be controlled by varying the number of antenna elements. It was found that the
beamwidth reduces exponentially with the increment of the number of antenna elements. |
