Abstract

This paper presents a novel pressure sensor consisting of a low-cost microstrip patch antenna placed a distance from a metal reflection plate. The pressure applied on the plate changes the distance between the metal plate and the patch antenna, which shifts the resonant frequency of the antenna sensor. The operation principle of the pressure sensor is firstly presented. Subsequently, the design and fabrication of the antenna sensor as well as the electromagnetic (EM) simulations of its response to the applied pressure are described. Finally, static experiments are performed to validate the performance of the pressure sensor and the results are discussed.
