A study into the use of polarisation diversity in a dual band 900/1800 MHz GSM network in urban and suburban environments

<title>Investigations on polarization schemes for use in wireless environments</title>

“…al. [18] also reported that horizontally separated V-polarized space diversity scheme outperforms the H/V and that the ±45° schemes and the ±45° scheme has a better performance than the H/V scheme. [19] have shown that the ±45° polarized antennas provide identical azimuth patterns and equal mean powers.…”

Novel logarithmically periodic planar antennas for broadband polarization diversity reception

“…It forms two decoupled receive channels with orthogonal polarization leading to uncorrelated output voltages at the feeding bridge of the antenna. Applying those dual polarized antenna structures in a wave field with uncorrelated polarization fading, orthogonal transmission channels may be formed, whose simultaneous use leads to an enhancement in quality of service [9][10][11][12]. The output voltages can be superimposed in a suitable combination network [13] in order to improve transmission performance due to diversity gain.…”
