MULTIPLE ANTENNA DIVERSITY FOR WIRELESS LAN APPLICATIONS

摘要

An antenna system comprising a plurality of antennas (70, 76, 140, 142) designed and oriented to provide one or more of radiation pattern, signal polarization and spatial diversity. The various diversity operational characteristics are achieved by using similar antennas physically oriented to provide the diversity attributes or by using dissimilar antennas (75, 76), that is, antennas having different radiation pattern and/or signal polarization characteristics.
