Development of Gas Sensors on Microstrip Disk Resonators

Procedia Engineering, 2014
Abstract Here it is reported about the development of microwave disk resonators and their employment as transducers in gas sensing devices. The sensors were developed by designing, modeling and realizing microstrip resonators on several microwave substrates, and by depositing sensing films on the disk.

Wideband Designs of E-shape Microstrip Antenna on Thinner Substrate

Journal of Microwaves, Optoelectronics and Electromagnetic Applications
Wider bandwidth microstrip antenna employing resonant slot require substrate thickness in excess of 0.07λg, which increases the antenna volume. In this paper, a novel technique to increase the bandwidth in E-shape microstrip antenna fabricated on a ...

High-Sensitivity Differential Sensor for Characterizing Complex Permittivity of Liquids Based on LC Resonators

Sensors
This paper proposes a high-sensitivity microstrip differential sensor for measuring the complex permittivity of liquids. The prototype of the differential sensor was formed by cascading two LC resonators on a microstrip transmission line based on stepped

Circular resonant structures in microstrip

Electronics Letters, 1969
Mode patterns of circular disc resonant sections are analysed. Radiation losses are expected to be small for the dominant mode, which would therefore have the highest Q value.

Multiresonator-Based Printable Chipless RFID for Relative Humidity Sensing

Proceedings, 2017
We present a chipless RFID for relative humidity sensing. It consists of three spiral resonators coupled to a 50 Ω microstrip line. One resonator is used for humidity sensing, and the other two are used for encoding ID.
