METHOD AND APPARATUS FOR REDUCING THE AMOUNT OF INTERFERENCE BETWEEN TWO ANTENNAE POSITIONED NEAR EACH OTHER IN AN ELECTRIC FIELD RADIO FREQUENCY IDENTIFICATION READER SYSTEM |
| 摘要 |
A typical reader system has at least a receiver (110), a first antenna (120), an exciter (130) and a second antenna (140). An electrically conductive shield (160) is positioned between the first antenna (120) and the second antenna (140) in order to reduce noise generated by the second antenna (140) and received at the first antenna (120).
