Summary: This paper presents a novel methodology for designing high-capacity frequency domain chipless RFID tags based on the backscattering principle. The tag consists of multiple square open-loop resonators loaded with a varying number of square metallic patches to form a mesh structure. The proposed tag encodes 16-bit data in a frequency band from 5.9 to 10.5 GHz and has a very high code density of 23.51 bits/cm(2) and a spectral efficiency of 3.47 bits/GHz. The design methodology is novel and leads to a very efficient chipless RFID tag that can be used in a variety of high-data-capacity applications.

Summary: The paper proposes a retransmission chipless tag with multiple U-shaped slot resonators to reduce the cost of traditional tags with chips. By designing different lengths of U-shaped slot structures, the spectrum notch depth of the resonator can be increased by reducing the slot width and spacing between resonators, or increasing the substrate thickness. The experimental results show that the spectrum notch depth of the resonator can be improved accordingly.

Summary: This paper presents design guidelines for displacement sensors based on spiral resonator tags. The sensor works by varying the coupling strength between the SR tag and a probing microstrip loop with the distance between them. The performance of the sensor depends on design parameters such as tag dimensions, filling factor, number of turns, and probe loop size. These guidelines can assist in selecting initial parameters according to the desired application requirements.

Summary: This paper presents a method for retrieving the phase and magnitude of the reflection coefficient in reflective-mode phase-variation sensors. The method utilizes a pair of rat-race hybrid couplers connected in a convenient manner and appropriately loaded with the sensing load. By expressing the reflection coefficient in terms of the ratio between the output voltage waves at two ports of the coupler pair, the expensive vector network analysers (VNA) can be replaced with low-cost voltage controlled oscillators (VCOs) and phase/amplitude detectors, making it more realistic for practical scenarios. The method is successfully applied to a simple reflective-mode phase-variation permittivity sensor based on a 90 degrees open-ended line, demonstrating its potential.
