Amplitude fluctuations in signals received over mobile radio channels are typically modeled by Rayleigh distribution. The field statistics in the volume of the enclosure are shown to correspond to the Rayleigh statistics found in properly functioning reverbration chambers when a sufficiently large number of modes are excited. The purpose of this paper is to show that the antenna efficiency can be measured accurately in much faster, easier and cost effectively reverberation chamber using three different antennas (two monopole antennas with attenuator and surface mount resistor, and modified folded monopole patch antenna). It also gives an investigation of the statistical characteristics in Rayleigh communications channels by using reverberation chamber. Scattering parameters taken from the measurement of the antenna radiation efficiency using reverberation chamber is implemented into Rayleigh Probability Density Function (PDF) model and it really shows that they are in good agreement with those of theoritically predicted Rayleigh model. 2008-09-12T07:15:19Z 2008-09-12T07:15:19Z 2006 Article Journal of Engineering Research and Education, vol. 3, 2006, pages 129-138. 1823-2981 http://hdl.handle.net/123456789/2187 http://www.unimap.edu.my/ en Kolej Universiti Kejuruteraan Utara Malaysia |
