This article walks through the basics and advanced principles related to how UHF RFID Passive tags communicate via backscatter. Before reading, it is important to know about the types of coupling and when each one is used. If you do not know what coupling is and how it works, please refer to " Principles of . See moreBackscatter is a method of communication in which an RFID tagwithout a battery (or any internal power source) receives energy from an RFID . See more

See moreWhen diving deeper into backscatter, it is impossible to leave out the presence and use of an electric field versus exclusively using a magnetic field. The three most used frequencies for RFIDare Low-Frequency (LF), High-Frequency (HF), and Ultra-High .

Backscatter is a method of communication in which an RFID tag without a battery (or any internal power source) receives energy from an RFID reader’s transmission and uses that same energy to send back a reply. The tag receives the energy via electromagnetic waves propagated from the reader/antenna.Passive RFID systems are composed of three components – an interrogator (reader), a passive tag, and a host computer. The tag is composed of an antenna coil and a silicon chip that includes basic modulation circuitry and non-volatile memory.See how inductive coupling and backscatter work - the principles of how passive RFID (including UHF RFID) works so that you don't need batteries on RFID tag. The low-power and low-complexity backscatter communications (BackCom), which simply relies on passive reflection and modulation of an incident radio-frequency (RF) wave, has emerged to be a promising technology for tackling this challenge.
Since there is not enough field power to operate a traditional RF transmission, passive RFID tags communicate back to the reader with a technique called ‘backscatter’. In effect, what the tag does is alter the impedance of the antenna match so that more or less energy is reflected. Passive RFID systems use tags with no internal power source and instead are powered by the electromagnetic energy transmitted from an RFID reader. Passive RFID tags are used for applications such as access control, file tracking, race timing, supply chain management, smart labels, and more.
Basically, backscatter communication is a technique that allows wireless nodes to communicate without requiring any active radiofrequency (RF) components on the tag [2]. In a conventional backscatter communication system (CBCS), there are two main components, called the wireless tag reader device (WTRD) and the wireless tag device (WTD), as .Passive RFID tags harness energy from an RFID reader’s emitted Radio-frequency (RF) signal. When the reader sends a signal, it creates an electromagnetic field that energizes the tag. The tag captures this energy and powers its internal chip, enabling it to transmit data back to the reader.A typical passive tag consists of an antenna and an application specific integrated circuit (ASIC) chip, both with complex impedances. The chip obtains power from the RF signal transmitted by the RFID reader. The tag sends data back by switching its input impedance between two states and thus modulating the backscattered signal.
RFID systems can be active or passive. On the other hand, a backscatter communication system is completely passive. In it, a reader is used to produce a continuous wave sinusoidal signal. Next, a passive device harvests this energy and uses it .
