General Specifications
For classic far-field applications with large reading distances, the Wide Range Antennas (WRA) are the optimal
choice: they are characterised by a very low axial ratio for circular polarisation, whereby the dependence of
reading results upon the position or alignment of tags is significantly reduced. For this reason, they are also the
ideal solution for portal applications in addition to many other application possibilities.
