Low range antennas
The low range antennas are a highlight of the new antenna series. With dimensions of 90 x 63 mm, these antennas
have a high field concentration in the near-field, with significantly reduced antenna gain in the far-field. With these
properties, the antennas achieve outstanding writing/reading performence at ranges of up to 10 cm with a typical
selectivity of 5 cm. Low range antennas are available in LoRa (Low Range) and ULoRa (Ultra Low Range). The
ULoRa was designed to read dipole-shaped tags (“far-field tags” at an extremely limited distance.
These antennas can also read loopshaped tags (“near-field tags”) up to 3 cm. The LoRa was developed for
larger ranges and is particularly suited to near-fi eld tags.

Mid range antennas
The MiRa 100° was developed for applications in the area between nearfi eld and far-fi eld. Particular importance
was placed on creating a compact construction to enable integration into environments with limited space. Read
ranges of over 2 m are still possible even with dimensions of 156 x 126 mm. MiRa also offers increased selectivity at
lower reading distances compared with conventional antennas. This antenna design is therefore also suitable for
use in the so-called transition area with a variety of transponder types
For short range to offer the S-MiRa antenna that is optimized with the same basic Paramenter for angle and trans-
mission level as our standard mid range antenna, small reading range to 1.0 m.

The SMSH 30-30-KRAI slave antenna was developed for applications in the field of point of sale, smart shelf ap
-
plications and Kanban solutions. The antenna is characterized by an extremely homogeneous read zone, which is
emitted by the high front to back ratio. Therefore it is suitable for static detection of multiple transponders. Due to
their extremely thin design, the antenna module can be integrated into different applications universal.
The antenna is equipped with an intelligent bypass circuit that allows for cascading up to 8 SMSH modules per
reader port. The control is done by a suitable © KRAI Kathrein RFID reader, the © KRAI control signals are trans-
mitted via the standard antenna cable
