RFID and distance measurement

Hello Guys,

I have a new project that I want use RFID to verify ID of item and I need measurement distance from reader to TAG. The maximum distance between the reader to TAG is about 7 cm and I want know distance between reader to TAG with accuracy about 1 cm.

Is it possible?

Sensor Sense: RFID for smart position sensing | Machine Design

But if you look at RFID tagging on a more-fundamental level, it's essentially a smart proximity sensor.

A proximity sensor detects the presence of a piece of metal and knows that a pallet has arrived at that location. Likewise, an RFID system also detects the arrival of a pallet. Except an RFID system can also determine what type of part is on that pallet by reading the identification code programmed into the tag. This does not mean...

Sensor Sense: RFID for smart position sensing | Machine Design

Robert Repas 1 | Nov 04, 2010

In most applications, radio-frequency-identification (RFID) systems are used to store product and process data on, or retrieve it from, a special RFID tag using wireless technologies. Power to operate the electronics in the tag comes from the RF energy of the interrogating transmitter. When powered, the tag transmits the programmed identifying information to the receiver. But if you look at RFID tagging on a more-fundamental level, it's essentially a smart proximity sensor.

A proximity sensor detects the presence of a piece of metal and...

How does a UHF RFID System Work?

The RFID reader emits radio waves of specific frequencies through RFID antennas. The waves "give energy" to the tags so that they can communicate by emitting a unique ID. They do not need batteries and can be used for many years. The reader processes the data so that we can integrate them into our...

Abstract--The efficiency of cold supply chain operations can

be improved with pervasive temperature sensing. In this paper,

we investigate the design of a low-cost, single-use RFID based

temperature threshold sensor that is capable of relating the

violation of a temperature threshold to a shift in the optimal

operating frequency at which the tag antenna is well matched

to the tag IC. This shift...

RFID systems can be broken down by the frequency band within which they operate: low frequency (LF), high frequency (HF), and ultra-high frequency (UHF).

LF RFID

The LF band covers frequencies from 30 KHz to 300 KHz. This frequency band provides a short read range of 10 cm, and has slower read speed than the higher frequencies, but is not very sensitive to radio wave interference. LF RFID...
