3 Product description
The ifm RFID antennas consist of several UHF antennas which can meet the requirements of almost any RFID application� The antennas are divided into three product lines with regard to their reading range: low-range, mid-range and wide­range antennas�
3.1 Low-range antennas
With dimensions of 90 x 63 mm the ANT810 / ANT910 low-range antennas have a high field concentration in the near field and an extremely reduced antenna gain in the far field� These features ensure that the antennas achieve ranges up to 10 cm with a typical selectivity of 5 cm�
In addition to the low-range antennas there is the ANT805 ultra-low-range antenna� The ultra-low-range antenna was designed to read dipole-shaped tags ("far-field tags") at a very limited distance� This antenna can also activate loop-shaped tags ("near-field tags") up to 3 cm� The low-range antennas were developed for larger ranges so that they are in particular suitable for near-field tags� The antenna allocation according to the reading range and tag shape is outlined in chapter 3�4�

3.2 Mid-range antennas
The ANT815 / ANT820 / ANT920 mid-range antennas were designed for applications in the range between near and far field� Special importance was placed on a compact design to ensure integration into space-limited environments� With dimensions of 156 x 126 reading ranges of more than 2 m are nevertheless possible� Mid-range antennas also have an increased selectivity at lower read distances as compared to conventional antennas� That means the mid-range antennas are suitable for use in the transition range with different tags�

3.3 Wide-range antennas
For the conventional far-field applications with reading ranges up to 10 m ifm offers the ANT830 / ANT930 wide-range antennas that are distinguished by a full width at half maximum of 70°� The circular polarisation usually required for UHF applications was significantly improved as compared to the antennas available on the market� The new versions typically attain an axial ratio of 1 dB that is used as reference for circular polarisation� The value common on the market, if specified at all, is approx� 3 dB�
The improved circularity leads to a considerably reduced dependence of the read results on the tag's position or alignment� Great importance was also placed on the front­to-back ratio of the antennas to reduce the influence of the close environment on the antenna properties� All antennas have an extremely high protection rating which guarantees their use in any industrial environment�
