“…The values obtained by the proposed model are better than the one depicted in [12] and [16]. If we analyze the complexity of prototyping and the physical dimensions of the tag, some reference designs like those mentioned in [11] and [13] can be compared with the proposed model. These designs cannot provide a long reading range, although the model mentioned in [11] has approximately the same gain as the proposed design.…”

In this paper, a high-performances microstrip antenna for UHF (ultra high frequency) RFID (radio frequency identification) tag is designed, prototyped and tested. The antenna consists of two main components: a 1.52 mm RT/duroid 5880 laminate substrate on which the antenna is designed and a 10 mm polytetrafluoroethylene (PTFE) dielectric material placed as a separator between the antenna and the reference ground plane for the microstrip antenna. With this structure, the RFID tag can reach a maximum reading distance of 19 m, although the antenna has a compact size of 80 mm × 50 mm . The long reading distance is obtained by attaching to the antenna an RFID chip that can provide a reading sensitivity of −20.5 dBm. The high bandwidth from 677 MHz to 947 MHz measured at −10 dB, makes the tag being usable worldwide especially for cargo container identification, the main purpose of this research.

“…Both tags provide good reading range but they have large sizes. Slot antennas are also used for metallic UHF tags [13]. This type of antenna has a complex design with a small gain (only 2.78 dB) that can provide a long reading distance of 11.5 m. The main disadvantage is given by the bandwidth which is narrowed (approximately 10 MHz).…”
