【摘要】 介绍了射频识别系统天线设计过程中涉及到的测量问题。通过自制校准件和测量板的方法测得了芯片阻抗,为标签天线的设计提供了目标阻抗。制作了一款弯折偶极子RFID标签天线,以此介绍了一种加反射板测量标签天线阻抗的方法。并将测量结果与仿真结果进行了比较,验证了这种测量方法的可行性。更多还原

【Abstract】 The problems of measurement during the design of RFID antenna was introduced.The impedance of tag IC is obtained by using calibration and measurement board,so the target impedance is provided for tag antenna.A RFID dipole tag antenna with meander-line is manufactured,and a measurement on the impedance of RFID tag antenna with a baffle-board is presented.Results of simulation and test show that this measurement method is feasible.更多还原
