Design of RFID Reader Antenna for Exclusively Reading One Single Tag
نویسندگان
چکیده
This paper presents a design of RFID reader antenna, which is equipped on a chipattaching machine producing the RFID tags. Such an antenna is constrained to read exclusively one tag only for the purpose of functional check of the whole tag when it passes the reader antenna, namely, the other neighbour tags on the same rolling band are ignored that time. A wideband microstrip antenna is designed and a fixture with shielding material is set up for such a reading constraint.

Antennas of RFID Tags
Radio Frequency Identification (RFID) is a rapidly developing technology which uses RF signals for automatic identification of objects. RFID system generally consists of three components: 1) A small electronic data carrying device called a transponder or tag that is attached to the item to be identified, 2) A reader that communicates with the tag using radio frequency signals, 3) A host data pr...
متن کاملDetection Probability of Passive RFID Systems under Cascaded Rician and Rayleigh Fading Channel
Radio Frequency Identification (RFID) system uses the principle of radiative power transfer between the reader and the tag antenna. The main performance metric for RFID system is the reliable reading coverage, where the tag can be read with higher detection probability. Most of current researches consider the reader coverage to be determined only by its read range assuming monostatic configurat...
متن کاملExperimental Studies of High-Accuracy RFID Localization with Channel Impairments
Radio frequency identification (RFID) systems present an incredibly cost-effective and easy-to-implement solution to close-range localization. One of the important applications of a passive RFID system is to determine the reader position through multilateration based on the estimated distances between the reader and multiple distributed reference tags obtained from, e.g., the received signal st...

In modern wireless communication systems, small circularly polarized microstrip antennas with good performance are desirable mainly at low microwave frequencies. The radio frequency identification (RFID) systems in the ultra-high frequency (UHF) band have gained much interest in many services [Finkenzeller2004]. The reader antenna is one of the important components in the RFID reader system and...
متن کاملRFID Applications and Challenges
Radio Frequency identification (RFID) is the popular wireless induction system [1-7]. The same as the general bar code identification, each RFID tag in an RFID system is assumed that equips a unique ID (UID) itself. A standard RFID system is consisted of Tag, Reader, and Application. When an independent RFID tag approaches the RFID antenna, the induc‐ tion between RFID tag and antenna happens. ...
