“…Although the tags in [2] and [5] had larger footprints than our tag had, they did not achieve better realized gain and reading distance. Further, these antennas have a three-layer design with radiating aluminum plates, making it more difficult to achieve impedance matching with the microchip.…”

“…The fundamental variables of the proposed antenna include the total length of the open and closed slots (L IP = L ip11 + L ip12 + L ip21 + L ip22 ), the width of the shorted inductive (W s ), the size of two slits (W ss ), and the total lengths of I-slot 1 (L IS1 = 2L is + V is ) and I-slot 2 (L IS2 = 2L is + V is ). For all evaluation cases, the proposed antenna was fixed at the middle of a metallic plate of size 250 × 250 mm 2 with a small open space of 0.1 mm. The aim of this study was to design a flexible and miniaturized tag structure whose conjugate impedance could be easily matched to that of a microchip through the modification of several parameter variables.…”

“…In particular, smaller RFID chips with lower power consumption, greater memory capacity, faster signal processing, wider design choices, and more secure data transmission are now easily available [1]. RFID devices are extensively used for applications such as toll roads, sensing systems, object tracking, supply chain management, and security systems [2], [3]. Generally, in a practical passive RFID system, each individual object is assembled with a small and low-cost tag.…”

This study developed a miniature tag antenna attached to a backing metal for ultrahighfrequency radio frequency identification (RFID) applications. The impedance of this antenna can be easily controlled at the desired fixed frequency by using different mechanisms and was not considerably affected by backing metal size. This antenna comprises a radiating patch with double I-shaped slots and a ground layer shorted to a narrow inductive plate. Loading a closed slot in the center of the patch and the open slits enabled flexible frequency tuning to match the complex impedance of the microchip used. This tag antenna has a low profile of 28.02 × 25.02 × 2.61 mm 3 (0.086 × 0.076 × 0.0079    ), and it provides a high power transmission coefficient of 99.74%, realized gain of −2.3 dB, and a reading distance of 8.1 m when it is located at the center of a metallic plate of size 250 × 250 mm 2 . The operational frequency of the proposed antenna was designed to reside the frequency bands for North and South America respectively). Measurements of the antenna prototype proved that the experimental results agreed with the simulated data.INDEX TERMS Metallic tag antenna, shorted inductive plate, reading distance, RFID tag, I-shaped patch.
