RFID readers and reader antennas work in combination to read tags and collect tag data. Reader antennas convert the electrical current from the RFID reader into electromagnetic waves that are radiated into space. When a tag antenna receives electromagnetic waves these are converted back to electrical current this way turning-on the chip. There is a large variety of reader antennas available.
Most common antenna types are linear- and circular-polarized antennas. Besides orientation issues the choice of antenna type is also determined by the distance between the RFID reader and the tags that it needs to read (read range). Reader antennas operate in either a “near-field” (short range) or “far-field” (long range).
We have a range of high quality RFID antenna’s from world leading manufacturers like Impinj, Kathrein and Times-7.
