“…In contrast to the above‐mentioned subtractive technologies, additive manufacturing techniques (inkjet, screen, and 3D printing) offer extremely low cost, completely digital, and highly scalable manufacturing processes . Due to these advantages, additive manufacturing techniques have been used to realize sensors, transistors, RF inductors, RF capacitors, RF filters, RF identification (RFID) tags, and so on. There have only been a few reports on printed RF switches .…”

be reconfigured to cover them, substantial space and cost savings could be achieved.(2) The wireless standards (frequency bands of operation) vary slightly in different parts of the world. In order to have a global device that can be adjusted to varying wireless standards in different parts of the world, the RF components need to be tuned to these frequency bands. Clearly, tunable or reconfigurable RF components are in demand. This tuning is typically done through an RF switch, which is capable of blocking or allowing RF signals to pass through it based on applied stimuli.Several kinds of technologies are used for RF-switching applications, such as a PIN diode-based switch, [1,2] a microelectromechanical-systems (MEMS)-based switch, [3,4] a transistor-based switch, [5,6] ferrite-and ferro-electric-based devices, [7,8] and so on. Each has its advantages and disadvantages; for instance, PIN diode switches feature fast switching speeds and longer operation life, but they can handle only relatively low power, and also they cannot work at very low frequencies.

A circular polarized patch antenna for UHF RFID tag-based sensor applications is presented, with the circular polarization (CP) generated by a new antenna shape, an asymmetric stars shaped slotted microstrip patch antenna (CP-ASSSMP). Four stars etched on the patch allow the antenna’s size to be reduced by close to 20%. The proposed antenna is matched with two RFID chips via inductive-loop matching. The first chip is connected to a resistive sensor and acts as a sensor node, and the second is used as a reference node. The proposed antenna is used for two targets, serving as both reference and sensor simultaneously, thereby eliminating the need for a second antenna. Its reader can read the RFID chips at any orientation of the tag due to the CP. The measured reading range is about 25 m with mismatch polarization. The operating frequency band is 902–929 MHz for the two ports, which is covered by the US RFID band, and the axial-ratio bandwidth is about 7 MHz. In addition, the reader can also detect temperature, based on the minimum difference in the power required by the reference and sensor.

“…A multiport microstrip patch antenna was proposed [16], one of which has a stack of thin-film solar cells for energy harvesting and the other port is assigned to the patch antenna to replenish the RF signal transmitted from the reader. Two antennas [49][50][51] were studied, one connected to the RFID chip to receive/transmit data from the reader and the other for RF energy harvesting, to power the digital circuits of sensors and microcontroller units (MCUs). In order to eliminate the need of two antennas, a circularly polarized patch antenna (CPPA) [52] was proposed, which utilizes the circular polarization (CP) generated by the new antenna shape to match the two chips with an asymmetric star-shaped slot microstrip patch antenna; one is as a reference node and the other can be connected to the sensor.…”

The integration of temperature sensor (TS) and UHF RFID technology has attracted wide attention theoretically and experimentally. The architecture, power consumption, temperature measurement range, accuracy, and communication distance are key indicators of the performance of UHF RFID temperature sensor chip (RID-TSC). This work aims to provide a clearer view of the development of UHF RFID-TSC integration technology. After a systematic analysis of the characteristics of ADC, TDC, and FDC used in an integrated TS, the key low-power technologies under different architectures are summarized. Through the observation of the latest researches and commercial products, the development trend of UHF RFID-TSC technology is obtained, including on-chip and off-chip coordination, multiprotocol and multifrequency support, passive wireless sensor intelligence, miniaturization, and concealment.
