Nondestructive Structural health monitoring (SHM) system using wireless sensor network is the one of important issue for aerospace and civil engineering. Chipless passive wireless sensor system is one of novel methods for SHM which uses the electromagnetic wave characteristic change by geometrical change of electromagnetic resonators or impedance change of functional material sensing part without RFID chip. In this paper, the chipless passive wireless SHM sensor using frequency selective surface (FSS) is investigated. Electromagnetic characteristic change of FSS by mechanical strain or structural damage is investigated by simulation and experiment.
