Description: Lack of standards and spotty frequency availability in the sub-11 GHz region has forced
many original equipment manufacturers (OEMs) and network operators to specify unique
custom antennas for base stations and backhaul in broadband wireless point-to-mulipoint
applications. While many of the resulting antenna designs have had merits, the lack of
volume production and field testing has often resulted in expensive, unreliable products.
With the continuing harmonization of the global frequency bands and some valuable
work conducted by the European Telecommunications Standard Institute (ETSI), a set of
high-performance broadband antennas that cover these harmonized frequency bands are
quickly becoming the industry norm. This article clarifies the important aspects of
WiMAX antenna requirements and provides representative WiMAX antenna models. Platform: |
