Capacity Improvement and Cell Range Extension By Multi-Beam Antenna

This work points out most problems and recommends some solutions to re-design a quiet small smart antenna panel with low cost and to improve capacity and optimise cell range by using adaptive multi-beam antenna techniques for telecommunication applications. The optimisation is possible with the help of algorithms such as Butler Matrix Arrays. A mathematical model to ideal antenna distributions is clearly mentioned. This has been achieved by the means of the near-field measurement techniques. The use of Fourier Transform (FT) techniques has been achieved to predict the far-field from the near field of an Antenna Under Test (AUT). The measurement process is precisely simulated and evaluated by using advanced engineering software such a MathCAD or Matlab program. Requirements and implementations to model the far-field from the near-field in one dimension, two dimensions and three dimensions are clearly highlighted.
