The spectrum domain ACLR and time domain RF envelope are tested at the antenna port with a PA output power of 32 dBm.Commercial readers usually use four antennas which are time multiplexed and can be used as transmitter and receiver. In this work a HF multiplexer for the USRP device is introduced. With this extension up to four trans-mit and receive antennas can be . An RFID (Radio Frequency Identification) reader is a device that uses radio waves to wirelessly communicate with RFID tags or transponders. These readers are essential components in RFID systems, enabling the retrieval and transmission of data from the RFID tags.
An RFID reader (interrogator) extracts the UID from the tag. A basic RFID system has three compo-nents: an antenna or coil, a transceiver with. RFID decoder, and an RFID tag pro-grammed with the UID. Table 1 shows the four commonly used RFID frequencies and their potential applications.RFID systems use radio waves to exchange information between RFID transponders, or tags, and interrogators or readers. How radio waves behave under various conditions in the RFID interrogation zone (IZ) affects the performance of the RFID system.
We report on the design of an enhanced EPC Gen2/ISO18000-6C-compliant UHF RFID reader with waveform optimization capability. By properly designing the powering waveform, e.g., a multisine (MS) signal, the power transfer to the transponders is improved, and therefore, the communication range is extended.Waveform optimization for UHF RFID systems has gained significant attention in recent years as a solution to improve the read range of RFID tags.
In the UHF RFID system, the reader sends information to one or more tags by modulating an RF carrier using amplitude shift keying (ASK) with a pulse-interval encoding (PIE) format. Tags receive their operating energy from the reader’s unmodulated RF carrier. We report on the design of an enhanced EPC Gen2/ISO18000-6C-compliant UHF RFID reader with waveform optimization capability. In this article, for illustration, three waveforms are tested with RFID Waveformer in a complex propagation environment: pulsed wave (PW) and time reversal (TR) modes compared to the traditional continuous wave (CW) mode.
