Passive Wireless Frequency Doubling Antenna Sensor for Strain and Crack Sensing
IEEE Sensors Journal(2016)
摘要
This paper presents the design, simulation, and validation experiments of a passive (battery-free) wireless frequency doubling antenna sensor for strain and crack sensing. Since the length of a patch antenna governs the antenna’s resonance frequency, a patch antenna bonded to a structural surface can be used to measure mechanical strain or crack propagation by interrogating resonance frequency shi...
