| Abstract: | Aiming at the problem of low strain measurement sensitivity of current microstrip antenna sensors,a composite matrix antenna sensor with an air layer was designed by studying the matrix structure.Combined with genetic algorithm,HFSS software was used to optimize the structural parameters of the sensor and to study the resonant frequency-strain relationship of composite matrix antenna sensor under the optimal solution.The designed composite matrix antenna sensor was subjected to a tensile comparison test,and its strain measurement sensitivity is 3.19 times that of the traditional microstrip patch antenna sensor.Both simulation and test results show that the composite matrix antenna sensor with air layer can improve the sensitivity of strain measurement. |
