The special geometric layout of actual engineering project requires the tag to be placed in a special metal cavity, which severely blocks the propagation of the electromagnetic (EM) field from the reader to tag. To guarantee the effective communication between the reader and tag, an innovative semicircular spiral antenna that works on 13.56 MHz with an effective working distance up to 100 mm has been developed to realize noncontact synchronous transmission of power and data from the reader to… 
Miniaturized Dual-Fractal Antenna Structure for RFID Tags
A design approach for the min iaturization of a dual-antenna structure (DAS) for radio-frequency identification (RFID) tag system is presented. The structure contains two radiating elements, one as a

Fork-shaped RFID tag antenna mountable on metallic surfaces
A low-cost novel antenna for radio frequency identification (RFID) tags mountable on metallic surfaces is presented. It is designed to work on a substrate FR4 that has a thickness of 3.2 mm and
A Novel Antenna Design for Passive RFID Transponders on Metal Surfaces
Metal poses a serious source of interference and loss of performance for RFID systems. This paper presents a novel antenna design for RFID transponder (tag) that enables long read/write range for
An RFID Tag Using a Planar Inverted‐F Antenna Capable of Being Stuck to Metallic Objects
TLDR
The designed PIFA, which uses a dielectric substrate for the antenna, consists of a U-slot patch for size reduction, several shorting pins, and a coplanar waveguide feeding structure to easily integrate with an RFID chip.
Compact slotted planar inverted-F RFID tag mountable on metallic objects
A compact slotted PIFA-type RFID tag (900 MHz) mountable on metallic objects is presented. The proposed structure can be easily matched to most microchips and facilitates their attachment on its
Energy Scavenging for Inductively Coupled Passive RFID Systems
TLDR
The theoretical estimation of the power by a loop antenna is derived, and the effect of the design parameters on the harvested power is investigated, showing that the power delivery performance is largely affected by the tag load at the reader.

An energy efficient data coding method and timing extraction for the RFID system
TLDR
A clock recovery scheme in which an IIR filter is combined with a PLL is proposed and can recover the clock quickly with long data dropouts, and achieves the same BER performance of ASK system with non-coherent demodulation as Manchester coding.
