The 3M UHF RFID ANTENNA is single-element patch antenna with a 63° beam width and Right Hand (RH) circular polarization.
This antenna has a typical gain of 9.0 dBic and is primarily used as an auxiliary read point antenna for the 3M Tolling reader in the 865–870 MHz ETSI band. The circular polarization makes this antenna most suited for use in situations where the orientation of the RFID tags is not known.
Box Size: 1
Unit Size: H12.0 x W12.0 x TH0.98 in (305 x 305 x 25 mm)
Features:
- The antenna radiation pattern is circularly polarized which allows the RFID tags to be placed in any orientation.
- This antenna has a broad 63° beam width and will provide the correct field pattern for a single standard vehicle lane width when mounted overhead at a height of approximately 8–12 ft (2.4–3.6 m) and with the antenna elevated to an angle of 5° to 30° towards the oncoming traffic flow.
- The antenna can also be used for side-fire (antenna mounted on the side of the lane) installations at a recommend height of approximately 6–8 ft.
