RFID TAGS WITH ENHANCED RANGE AND BANDWIDTH OBTAINED BY SPATIAL ANTENNA DIVERSITY |
| 摘要 |
Spatial antenna diversity is used with RFID tags to reduce sensitivity to multi-path fading. RFID tags can use a single multi-port chip or multiple multi-port chips. The ports of the chip or chips are coupled to separated feedpoints on one or more antennas.
