900M ultra-high frequency RFID circular polarized ceramic antenna launched by Yifan Cloud Technology includes three models: YF3535-CA (1.5dbi), YF-5050-CA (3.5dbi), YF-120120-CA (5dbi), with our company's ultra-high frequency RFID module YF100 (26dbm), the effective reading distance of the card is 1 meter, 2 meters, 7 meters. Compared with other antennas, this type of antenna has no requirements on label direction, small blind area, wide card reading range, stable performance, and better adaptability to the environment.
