2. Introduction
2.1. RFID UHF antenna
The new Kathrein antenna family consists of various UHF reader antennas, which can meet the needs of virtually
any RFID application.
The antennas are divided into three product lines with respect to the reading range: low range, mid range and wide
range antennas.
This allows to up 4 antennas are used simultaneously in any combination with Kathrein RFID reader. This modularity
is only possible with Kathrein RFID readers and antennas.
0 to 10 cm - with Low Range antenna
20 cm to 2 m - with Mid Range antenna
1 m to 10 m - with Wide Range antenna

3. Product description
3.1. 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 eld concentration in the near-eld, with signicantly reduced antenna gain in the far-eld. 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-eld tags” at an extremely limited distance.
These antennas can also read loopshaped tags (“near-eld tags”) up to 3 cm. The LoRa was developed for
larger ranges and is particularly suited to near- eld tags.
3.2. Mid range antennas
The MiRa 100° was developed for applications in the area between near eld and far- 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.

Figure 3: Short-Mid range antenna
The SMSH 30-30-KRAI slave antenna was developed for applications in the eld 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

3.4. Wide Range antennas
For the standard wide range applications with read ranges up above 10 m Kathrein offers wide range antenna
types, which are characterized by a beam width of 70° (WiRa 70), 40° (WiRa 40) and 30° (WiRa 30) and a cir-
cular or linear polarization

WiRa 70 ETSI 52010078 70° circular 865 – 868 MHz
WiRa 70 FCC 52010079 70° circular 902 - 928 MHz
For standard UHF applications a circular polarization is used, when the orientation of the transponders is not
known, or may occur a randomly. This circular polarization was signicantly improved in comparison to the an-
tennas available on the market. For the so-called axial ratio, which is used as a characteristic value for circular
polarization, the two new models achieve typical values of 1 dB. If speci ed at all, the usual value on the market
lies at around 3 dB. The improved circularity of the Kathrein wide range antennas leads to a signicantly reduced
inuence of the read results caused by the position or orientation of the transponder.
Linearly polarized antennas are used for UHF applications, if the orientation of the transponder is xed and well
dened. In this case, the lower polarization loss of linear antennas will lead to bigger read range.
Great importance was also placed on the front-to-back ratio of the antennas to reduce
the inuence of the adjacent (installation) environment on the antenna properties.
All antennas have an extremely high protection class which guarantees problem-free use in any environment.
The use of high-quality materials for a long service life and high levels of reliability contribute to the optimal perfor-
mance provided by the antennas under even the most challenging of conditions.

3.5.2. © KRAI PLS (Polarisation Switching-) antenna
With the © KRAI PLS-Antenna, build as a WiRa 70° Antenna, the polarization can be switched static or dynamically.
The following settings are possible in any combination:
- Circular LHCP
- Circular RHCP
- Linear horizontal
- Linear vertical
For Wide Range application the best polarization can be selected. A exible adjustment of the antenna on site is
possible.
In addition the read rate can be increased via the switching circular LHCP / RHCP by up to 30%.
For direct access programming 4 LEDs are free for visualization.

3.5.3. © KRAI CSB (Circular Switch Beam-) antenna
With the ©KRAI CSB-Antenna, build as a WiRa 30° antenna, the antenna beam can be switched static or dynami-
cally. The following settings are possible in any combination:
- Antenna beam initial position (radiation 90°of the Antenna)
- Antenna beam switched 35° to the left
- Antenna beam switched 35° to the right
The orientation of switching is in the longitudinal direction of the antenna. On the connector side of the antenna the
position “RIGHT” is dened.
These CSB antennas are used to detect the movement of the transponder. This information will be transferred in
combination with the collected transponder is. With 5 antenna sweeps per second, two or more reads are used to
determine the direction of movement.

3. Product description
The correct combination of reader antenna and transponder is essential for every RFID application. The correct
selection ensures a high read rate and reliable operation of the system.
The LoRa and ULoRa antennas can read loop-shaped, hybrid-form and dipole-form transponders up to 10 cm and
offer a very well de ned read range.
The Smart shelf and SMIRA read the hybrid transponders at distances up to 10cm and the dipole type transponders
at distances up to 100cm.
MiRa can read loop-shaped transponders up to 30 cm, hybrid-form transponders up to 100 cm and dipole-form
transponders up to several metres.
The WiRa antennas ans WiRa-30-CSB-KRAI antennas are designed for typical dipole-form transponders with read
ranges of up to 10 m, but they can also read loop-shaped and hybrid-form transponders at a short distance.
The typical read ranges of the antennas described can be seen in the following gure. If WiRa 30°
and WiRa 70° are operated with the same ERP, the maximum ranges of the two antennas are equal,
although the WiRa 30° has a higher selectivity.

Note
To achieve the best reading and writing results, we recommend operating the Kathrein UHF RFID reader an-
tennas exclusively with UHF readers from Kathrein.
As a further option, it is possible to integrate the modular Kathrein RFID UHF reader latform in the WIRA antennas
to also provide a powerful single read point for certain applications. As a result of the consistent continuation of the
platform strategy for antenna and reader, all product and interface variants already introduced are available in nu-
merous combinations. Cost-ef cient adaptation to varying customer requirements is therefore possible as a result.
For all variants protection class IP 67 and an operating temperature range from -20 to +55 °C apply. A TNC socket
is used as the antenna interface on all types.
