Abstract
Abstract
With the popularization and application of RFID sensors, the energy supply of internal circuits is a key problem. When multiple monitoring quantities are involved, the traditional energy extraction method of RFID sensors often leads to insufficient energy. Therefore, this paper designs an RFID sensor integrating acceleration and temperature sensing parameters, and proposes a cross placed dual antenna scheme. In order to increase the concentration of antenna radiation energy, a metal reflective aluminum plate is added. Through experimental tests, it is proved that the scheme can well optimize the radiation direction and performance of the antenna.
