A Microwave Pressure Sensor with Wire Interconnection for Metal Cavity Environment

Abstract

The article presents a wire interconnection microwave pressure sensor for metal cavity or metal cavity-like environments. We designed the configuration of the sensor by HFSS simulation firstly, and then fabricated a concept-proofed copper device. Finally, we constructed a close metallic cylinder and tested the pressure sensing performance of the device. Experimental results proved our solution that could function well. Our work gives a new choice of pressure detection for close metal surroundings.
