摘要
The two kinds of polymer-derived SiAlCN ceramics resonant cavity wireless passive temperature sensors with and without patch antenna were designed. Their maximum wireless detection distances were obtained through simulation and calculation. Through the simulation of reflection and re-radiation characteristics of the two kinds of sensors, the mechanism of the integrated patch antenna on increasing the detection distance of the sensors were revealed. The sensors were fabricated and measured to verify the method. The results show that, compared with the sensor without the patch antenna, the maximum detection distance of the sensor with patch antenna was increased from 18 mm to 32 mm. And integrated patch antenna has almost no effect on the characteristics of the sensor's resonant frequency change with temperature. It demonstrates that the method of integrating patch antenna is an effective way to increase the wireless detection distance of the resonant cavity wireless passive sensor.
