“…This single band antenna is suitable for RFID applications in UHF band at operating frequency ranging from 902 MHz to 928 MHz. In Figure 11, as for multi-band antenna, the chosen reflection coefficient values are −20 dB, −38 dB and −25 dB for the operating frequencies of 915 MHz, 1.6 GHz and 2.45 GHz, respectively [14]. Figure 12 shows the polar radiation patterns of E-and H- 3-D omni-directional radiation pattern of the corresponding antenna is shown in Figure 15.…”

Abstract-This paper presents a mini multi-band printed omnidirectional antenna with v-shaped structure for radio frequency identification (RFID) applications. The proposed multi-band antenna is developed from the initial v-shaped design which is only capable of working as a single-band antenna. By deploying a concept of dipole antenna to an initial design, the proposed antenna is accomplished to operate with two different modes of RFID system which are passive and active modes at frequencies of 915 MHz and 2.45 GHz respectively. The passive RFID tag is invented when a chip of Ultra High Frequency (UHF) is integrated with a proposed multi-band antenna. This passive tag, which is able to radiate with the measured signal strength, shows that the reading ranges are boosted almost two times compared to the conventional inlay antenna. The maximum reading range of passive RFID tag with inlay antenna is 5 m, though a reading range up to 10 m is achievable through the deployment of the proposed antenna at a measurement field. Implicitly, the measurements carried out on the antenna are in good agreement with the simulated values. Moreover, the size of the mobile passive RFID tag has been substantially as 100 mm × 70 mm, even though the antenna is fabricated with an inexpensive FR-4 substrate material. With the reasonable gain, coupled with cheaper material and smaller size, the proposed antenna

“…In this paper, we introduce a campus attendance system using 2.45GHz active RFID technology, which can judge the direction of students entering and out of the campus with real time. In the early days, the technology systems were used for vehicle management in roads or parking lots [5,6]. In the vehicle management system based on RFID technology, a RFID antenna is usually defined as 0 or A, and another RFID antenna is defined as 1 or B, from 0 (A) to 1 (B) is in-state, from 1 (B) to 0 (A) is out-state.…”

In order to solve the problem that a large number tags motion direction judgement in campus long distance attendance system based on 2.45GHz active RFID technology, a technical test system was designed and constructed in this paper, the RSSI of the student tags through the technical test system obtained by two antennas. Then this paper analyzed the data characteristics, and proposed 2.45GHz active RFID card motion direction judgement algorithm based on RSSI distribution. Finally, 1000 student tags are used to experiment, and the experimental results shown that the effective judgment rate of the algorithm reaches more than 99.9%.

“…In this sense, the reading zone is a statistical concept since at, its border, signal suffers fast degradation and is influenced by background noise. Although such limitations, the use of RSSI (received signal strength indication) [18,19,20] characterizes the reading zone [21]. In tolling applications [22,23] vehicles of different types must be correctly identified and charged.…”

This work discusses the RFID reading contexts of targets in 1-d motion. The problem to be solved is a function of the final reading rate that can be optimized. A set of variables constitutes the parameter group extracted from a simplified Friis model taking into account the presence of obstacles such as ground and its electromagnetic properties. The speed influence of targets in motion (containing RFID tags) is also discussed since it directly affects the final number of readings for the reader-tag pair, given an input power.
