The UL-9001-333 RFID/Low Power application antenna and RF coupler was developed in response to catalog visitor requests. This antenna was designed for use in close proximity of or near RFID tags, particularly when the tag is placed on a large body, capable of detuning commonly used RFID reader antennas.
Exposed metal surfaces within the antenna are grounded to the RF connector's shield, as a precaution, in the unexpected event there are combustible gases present. Only the RF connector's center conductor, and its associated 2.5 cm (1") track of transmission line are not grounded. Such node is isolated to 50 Volts DC at ground level (altitude = 0 m), and within the specified temperature range.
Normal uses of the UL-9001-333 are as:
- RFID reader antenna, operating within US 900 MHz ISM band (902-928 MHz), or within EU unlicensed band 868 MHz
- Cellular Phone test fixture RF coupler, operates best at cellular 800 and 900 MHz bands
- Embedded or exterior antenna for 800/900 MHz portable, and small devices
