Abstract The industrial wireless sensor networks may suffer serious random fading of wireless channel in industrial environment which is induced by the metallic equipments and apparatus. By analyzing the radio signals in industrial environment, an antenna attitude optimized system is presented based on the polarization diversity technology considering the limitation of size and cost for wireless sensor networks. The performance comparison between selection-diversity system and antenna attitude optimized system is carried out, and an antenna optimization scheme is put forward suitable for wireless sensor networks, with high effectiveness verified by measurements in actual industrial environment.
