چکیده

A very small UHF band RFID tag antenna using ceramic material mountable on metallic objects is presented. The proposed tag size is 25x25x3 mm. The impedance of the antenna can be easily matched to the complex conjugate of the tag chip impedance from the size of the shorting plate of the side patch and the size of the feeding loop. The antenna satisfactorily operates on metal plates, so it is applicable in many applications. The proposed design is verified by simulation and measurements which show good agreement.

Analysis of Low Profile UHF RFID Tag Antennas and Performance Evaluation in Presence of a Metallic Surface

Passive UHF RFID systems have drawn considerable attention because these can provide a long reading range, high data rate and small antenna size. However, a passive UHF RFID system has challenges in tagging a metallic object due to the effects of conducting materials on the tag antenna performance. This paper proposes two widely used label-type antennas: folded dipole antenna and meandered dipo...

A Slim Wideband and Conformal Uhf Rfid Tag Antenna Based on U-shaped Slots for Metallic Objects

A slim wideband patch antenna designed for the ultrahigh frequency (UHF) band radio frequency identification (RFID) tag is presented in this paper, which can be mounted on flat or curved metallic surfaces directly. The presented antenna is fabricated on a very thin (only 0.5 mm) and low-cost PET substrate (εr = 3.8, tan δ = 0.02). The proposed design consists of tow coplanar patches radiation u...
