中文摘要：

针对天线在ISM和UNNI频段的应用，提出了一种采用共面波导馈电的新型单极子双频天线，在传统T型单极子天线上平行加载辐射贴片实现双频工作。分析了天线尺寸变化对工作频率的影响，得出所设计的天线频率比在1．67～2．67范围内可调。制作加工了工作于ISM／UNNI频段的天线实物，测试结果与实验结果吻合良好。天线全向辐射性能良好，分别在低频段和高频段获得了21.28％和3．9％的相对带宽（S11≤-10dB），适用于无线通信领域。

英文摘要：

For the application of antenna in ISM and UNNI bands, a novel monopole dual - band antenna using CPW- fed is proposed. A radiation patch is loaded on a traditional T - shaped antenna to realize operating in dual - band. The effect of antenna size on frequency is analysed, which shows that the frequency ratio can be tuned from 1.67 to 2.67. An antenna worked on ISM/UNNI bands is fabricated and measured, and the measured results are in good agreement with the simulated results. This antenna has a good radiation capability of full- direction, and it has gained a relative bandwith of 21.28% and 3.9% at the lower and higher frequency respectively（ S11≤ - 10 dB）, so it is suit for wireless communication field.
