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).
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 QuasarMF. 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 QuasarMF. 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. Necessary cables are therefore 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.
