为满足RFID天线小型化要求，提出一种基于LTCC技术的新型天线。所设计天线的体积仅为7．8×8．62×0．8mm。仿真结果表明天线具有良好的全向性和宽频带特性，在2．4~2．5GHz频段反射损耗小于-10dB。本文还研究了介质常数等参数对天线性能的影响。

In order to meet the miniaturization trend of radio frequency identification (RFID) tag antenna，a novel antenna structure based on L TCC technology is proposed．The dimension of the RFID tag antenna are 7.8×8.62×0.8mm．Simulated results show that the proposed antenna has the characteristics of omni -direction and wide bandwidth．Its measured return loss is less than - 10dB in the range 2.4 to 2.5GHz．We also studied the influence of dielectric constantεon the characteristic parameters of antenna．
