چکیده
The issues of high costs and sophisticated circuit structures limit applicability traditional chipped sensors. This paper innovatively designs a chipless sensor based on the split-ring resonator combined with temperature-sensitive material as substrate. alumina ceramics are used sensitive for reflecting environment temperature in accordance its characteristic that dielectric constant increases monotonically rising temperature. simulation demonstrates resonant frequency decreases from 8.58 GHz to 8.22 an offset 0.36 sensitivity 0.9 MHz/°C variation 500 °C 900 °C. designed this has good resonance characteristics, is wireless, passive, low cost, planar structure, suitable various harsh environments.

Microwave Backscatter-Based Wireless Temperature Sensor Fabricated by an Alumina-Backed Au Slot Radiation Patch
A wireless and passive temperature sensor operating up to 800 °C is proposed. The sensor is based on microwave backscatter RFID (radio frequency identification) technology. A thin-film planar structure and simple working principle make the sensor easy to operate under high temperature. In this paper, the proposed high temperature sensor was designed, fabricated, and characterized. Here the 99% ...
متن کاملDesign, Fabrication and Measurement of Two-Layered Quadruple-Band Microwave Metamaterial Absorber
The design, simulation, fabrication, and measurement of two structures of metamaterial absorbers (MA) is investigated at microwave frequency in this paper. By stacking of one layer structure on the top of each other, a two-layered structure is generated. The unit cell at each layer consisting of two sets of various circular and square patches are designed so that the structure exhibit quad band...

متن کاملMullite-alumina functionally gradient ceramics
Cracks free mullite-alumina Functionally Gradient Ceramics (FGC) have been obtained by sequential slip casting of Mullite-alumina slurries with diserent mullite/alumina ratios. These slurries were prepared with 65 % solids content and viscosities rangingpom 10 to 40 mPa.s. 7he presence of cracks perpendicular to the FGC layers have been attributed to residual stresses developed because of the m...
