Abstract

In this paper results are presented for a simple yet highly sensitive transceiver for phase modulated RFID applications. This is an advance on other simple RFID readers which can only operate with amplitude shift keyed (ASK) signals. Simple circuitry is achieved by the use of a novel injection locked PLL configuration which replaces the standard superhet type architecture normally used. The transceiver is shown to operate with a number of phase modulation modes which have certain advantages relating to distance to target. The paper concludes with practical results obtained for the transceiver when operated within a backscatter RFID application. A unique advantage of this transceiver is its complete immunity to the problem of TX/RX isolation, allowing for long ranges, estimated to be in the region of 80m at 1 GHz, to be achieved even in the presence of a simple backscatter target.
