摘要
针对基于RFID的金属手术器械管理过程中存在标签不能正常工作的问题,提出了一种利用金属手术器械表面作为标签的天线与读写器天线进行信息交流的方案。方案中无天线标签与金属手术器械可以看成由该标签激励的半波偶极子天线,并利用HFSS软件对半波偶极子天线进行仿真分析,以便于选取天线的最佳匹配。最后,通过实验验证所提出的方案用在基于RFID的金属手术器械管理系统上的有效性。
Aiming at the problem that the label can not work properly in the management process of metal surgical instruments based on Radio Frequency Identification(RFID),the paper presents information exchange a reader of and an antenna shich uses the surface of metal surgical instrument as a label.In the scheme,no antenna tag and metal surgical instrument can be regarded as a half-wave dipole antenna excited by the tag,and the half-wave dipole antenna is simulated and analyzed by HFSS software,so as to select the best match of the antenna.Finally,the effectiveness of the proposed solution for RFID-based metal surgical instrument management systems is verified by simple experiments.
