Self-decoupling antennas are designed in this paper. The decoupling principle is based on a weak field created by a T-shaped feeding line (TSFL) and the antenna element itself. When arranging another identical antenna in the weak field, high isolation between two antennas can be achieved without adding extra decoupling structure. First, the weak field of a single antenna is described and analyzed by the equivalent circuit. Then, the adjacent antenna is placed in the weak field to obtain a high isolation level of 51 dB between two-element MIMO antennas. Furthermore, a four-antenna linear MIMO was designed, which also achieved high isolation. With the merits of simple structure and efficient decoupling, these self-decoupling antennas are promising for MIMO UHF RFID Systems.

In this paper, we investigate how the incident power at the tag affects the backscattered signal that reaches the reader. It is shown experimentally and theoretically that the backscattered complex signal, i.e. magnitude and phase, changes significantly with respect to the incident power at the tag’s antenna. This effect is neglected in prior art and is due to the change of the input impedance of the tag’s front end, due to the presence of non-linear components, like the rectifier’s diodes. Measured deviation of 14dBs and phase shift of 100 degrees is reported herein. These variations might lead to large localization errors, depending on the method and the measured quantity, unless the localization algorithm accounts for the expected variability.

A circularly polarized antenna is presented for 2.45/5.8 GHz RFID readers in this paper. The antenna comprises of a cross-dipole structure with dipole pairs designed on lower and upper sides of the antenna substrate. The dipole elements are connected through two delay lines to introduce a 90-degree phase difference between the current vectors. The antenna exhibits an impedance bandwidth of 220 MHz (2300 2520 MHz) in the 2.45 GHz band and 200 MHz (5700 5900 MHz) in the 5.8 GHz bands. The axial ratio bandwidths are 170 MHz (2410 2580 MHz) in the 2.45 GHz band and 80 MHz (5790 5870 MHz) in the 5.8 GHz band.

In this paper, we present a prototype algorithm for tracking and following a moving target through RFID technology by a robot. The robot is equipped with two front facing antennas, which collect phase measurements of the tag’s modulated signal. We consider a direction-finding algorithm, based on particle filter theory, which exploits the phase-measurements to assign weights to the particles. The proposed track-and-follow robot is successfully tested in a laboratory environment and will be deployed inside a museum.

This manuscript prescribes the design of a four-port ultra-wideband (UWB) diversity antenna combined with 2.4 GHz ISM radio band. The denim-based wearable antenna is intended for use as a radio frequency identification (RFID) tag for tracking and security applications. The unit cells of the antenna are arranged orthogonally to each other to achieve isolation $gt15$ dB. The bending analysis of the proposed antenna is performed to ensure its stability. The dimensions of the unit cell and four-port MIMO antenna are $30 times 17 times 1$ cubic millimeter and $55 times 53 times 1$ cubic millimeter, respectively. The proposed antenna’s specific absorption rate (SAR) is researched in order to determine the safer SAR limit set by the Federal Communications Commission (FCC).

The RF tags offer ultra-low power cost of the communication due to the passive receiver based on envelope detector. The tag-to-tag link requires presence of excitation signal, either as a dedicated continuous wave exciter or an ambient RF signal. However, the link suffers from the limited range. The capability of RF tags to passively estimate the amplitude and phase of the wireless channel between pairs of communicating tags empowers these passive tags to provide a real-time, precise, fine-grained RF fingerprint of the environment. The phase estimation also enables collaboration between neighboring tags in order to improve the range and robustness of tag-to-tag link itself. We propose strategies that through the use of optimal collaborative reflection and backscatter of a cluster of tags improve the link range. We demonstrate that a single tag on a distance of 16 cm from the transmitting tag with optimal collaborative reflection improves the link range by 40%.

Contextual information of mobile devices is necessary in location based services. This location information is used in extending tracking objects or navigation services from outdoor to indoor. High quality services are provided by GPS in outdoor applications. Since GPS is not providing accurate positioning in indoor many researchers move on to indoor positioning with different technologies like Blue Tooth, UWB, WiFi and RFID. RFID based positioning is preferred due to low cost devices and improved accuracy. This proposed system is focused on Received Signal Strength measured from RFID tags. An experimental result shows better improvement when compared with regression and Gaussian algorithms. It can be used in real time applications for Location identification.

Music has always been an important way of expressing ourselves. Creating music from bodily interaction has gained lots of attention: Various gestures, body touch, movements of hand and foot are used as inputs for creating music. The traditional identification and sensing technology, passive ultra-high frequency (UHF) radio frequency identification (RFID) technology, can also be turned into a music player textile for creating music with simple touch or gesture on clothing. When the player touches a specific integrated circuit (IC) copper pad with finger, the unique ID is read by the reader and translated to music via our music software. With this preliminary version of the music player textile, it is possible to play drum and piano. In the future, the technology can be applied to daily clothing for educational musical purposes such as teaching music to kids, as well as professional musical purposes such as performers (showmen and hosts) and lecturers to have playful performances.

In this paper, a bi-directional coplanar-waveguide (CPW)-fed antenna with circular polarization (CP) is presented for radio frequency identification (RFID) reader applications. By incorporating an inverted L-shaped arm at the left side and a and tuning stub at the right side of ground plane in a conventional CPW-fed monopole antenna, a wide impedance bandwidth and axial-ratio bandwidth (ARBW) is achieved. The antenna geometry is square in shape and printed on one side of FR4 substrate only, which consumes an overall dimension of $60 times 60$ mm2 with a thickness of 1.5 mm. The antenna is simulated and the simulation results shows an impedance bandwidth $(mathrm{S}11 lt -10$ dB) of 40.2% (2.18–3.28 GHz) and ARBW ($lt3$ dB) of 28.3% (2.03-2.7 GHz), respectively. The peak gain of the proposed antenna is 3.17 dBi in both ±Z direction. The antenna is suitable for Internet of Things (IoT) based RFID applications.
