Polarization Diversity Antennas for Compact Base Stations

摘要

This article describes the use of diversity reception for mobile radio base stations and compares the performance of space and polarization diversity techniques. In urban areas polarization diversity offers performance that is generally comparable with that of space diversity. The compact three-antenna system of a polarization diversity base station is much more acceptable as a feature of the urban landscape. Performance trials in rural areas show a less clear picture: While most experimenters report that space diversity is a superior method, others have obtained results favoring polarization diversity. This article discusses possible reasons for these differences.
