Mobile Communication Antennas in Uniform and Gaussian Propagation Channels

In this paper, diversity performances are compared using two different propagation channel models. The models of interest are the statistically uniform and Gaussian ones. Very compact antenna systems that consist of two printed monopoles are used. At such terminals, antennas are so closed to each other that envelope cross-correlation coefficients are low whatever the channel model used. Diversity gains are then independent of correlation coefficient. Any difference of performances may then come from mean effective gains, so from Mean Signal level of each antenna in the channel models. After, parametrical studies of Gaussian environments point out enriching conclusions.
