5 Antenna Connection
To send and receive data to and from the tags an appropriate HF RFID antenna (13.56 MHz,
50 Ohm) has to be connected to the reader. This is done via the BNC connector on the
reader (X1).
ATTENTION
To avoid overheating and also destruction of the antenna it has to be
designed for RF power of at least 2 W.
Since the design of HF antennas can be a task requiring expert knowledge, metraTec RFID
Solutions offers a range of standard antenna types for HF applications which are compatible
to the QuasarMR1. Further, we offer an antenna design service for custom designs. Most
antennas come equipped with standard BNC connectors which can be directly connected to
the QuasarMR1. In cases in which a different antenna geometry or connector is needed
please contact [email protected].
To connect the antenna to the reader or multiplexer the devices are equipped with BNC
jacks and the cables are equipped with BNC plugs at both ends. When connecting antennas
with multiplexers or readers please keep in mind that the cable has a signal dampening
effect reducing the HF power reaching the antenna. If long cables are to be used in
connection with one or more multiplexers the reading range can be reduced measurably.
Using higher quality cables can reduce the power loss in cases in which this is important.
Recommended cables with different lengths can be ordered from metraTec as accessories.
ATTENTION
Always connect an 50 Ohm antenna as described above first, before
powering the device. Powering the reader without an appropriate 50 Ohm
load for a longer time could damage the reader permanently.
