主要阐述基于复合左右手传输线（CRLH TL）零阶谐振模设计小型化宽频带的手机天线。该天线低频段由尺寸较大的零阶谐振天线决定，高频段由尺寸较小的零阶谐振天线决定，尺寸较大的零阶谐振天线的右手模式与尺寸较小的零阶谐振天线的零阶谐振模谐振在相邻的频带上实现频带融合，从而扩展高频段的带宽。该天线覆盖了GSM900、PCS、UMTS、Bluetooth和ISM2400五个移动通信频带，天线厚度仅为1mm，所占面积为37×15mm2。测试结果与仿真结果吻合，满足移动通信终端对手机天线的要求。

In this paper, the miniaturized broadband phone antenna is designed based on composite right/left-handed transmission line (CRLH TL) zeroth-order resonant (ZOR) mode. The low frequency of this antenna is determined by the longer ZOR antenna, while the high frequency is determined by the shorter ZOR antenna. The right-handed mode of the longer ZOR antenna and the ZOR mode of the shorter one can be merged to extend the bandwidth of high band if their resonant frequencies are adjacent. The antenna covers GSM900, PCS, UMTS, Bluetooth and ISM2400 frequency bands. Its thickness is only 1mm and its area is 37×15mm2. The test results agree well with the simulation results, which meets the requirements of mobile communication terminals for phone antennas.
