When 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 . See moreAbstract: The interest in wearable antenna design has increased significantly due to its . 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.Abstract: The interest in wearable antenna design has increased significantly due to its potential applications for humans, especially in the context of RF identification (RFID) technology. RFID transponders can wirelessly transmit identification numbers or sensor data over short distances.

Data exchange between RFID reader and tag can employ various modulation and coding schemes (e. g. amplitude modulation and Manchester coding). The signal transmitted on the forward link (reader to the tag) contains both continuous wave (CW) and modulated commands as shown in Figure 2.A viable, simple, and power-efficient solution is to equip RFID tags with retrodirective arrays, which guarantee reflection with maximal gain in the direction of incidence. In this paper, we design and implement an original retrodirective tag in which its feeding network is a properly-terminated rat-race coupler.The tag is composed of an antenna coil and a silicon chip that includes basic modulation circuitry and non-volatile memory. The tag is energized by a time-varying electromagnetic radio frequency (RF) wave that is transmitted by the reader. This RF signal is called a carrier signal.
This paper proposed a novel tag circuit design for amplitude-shift keying (ASK) modulation. Instead of using the conventional resistive modulator, we proposed a reactive modulator for impedance matching and backscattered signal modulation. Modern diodes can operate up to over 1 GHz, allowing passive RFID tags to demodulate a reader signal using only a diode and capacitor. Unmodified OOK is admirably simple and seems promising as a method of modulating areader signal.During uplink and downlink communication, the reader’s radio frequency (RF) carrier wave energizes the RFID tag via power harvest-ing. Uplink communication occurs by modulating the antenna loading (via switching of a on-chip variable impedance) [5].The procedures used in RFID systems are the digital modulation procedures amplitude shift keying (ASK), 2 frequency shift keying (2 FSK) and 2 phase shift keying (2 PSK). The use of a modulated subcarrier is widespread in radio technology.
