Simultaneous comparison of linear and circular polarisations at 11.6 GHz on a terrestrial link
Abstract
Preliminary data from an 11.6-GHz, 18-km terrestrial radio link operating in linear vertical, horizontal, and circular polarizations are presented. Both rain events and 'clear weather' multipath events are analyzed and cumulative statistics presented over a 9-month period. It is evident that both linear polarizations produce better polarization isolation performance than the circular. Rainfall events appear to limit the circular polarization usage whereas multipath events limit the linear polarization. Good agreement with theoretical models for rainfall is obtained on both polarizations.
