中文摘要：

随着无线通信系统的发展,天线的尺寸和工作的灵活性受到广大科技工作者的广泛关注,但现存设计中存在着天线的尺寸过大、重构方式不便、工作频率可调节实现困难等缺点,为此设计了一款工作频率可调节的天线。基于复合左右手传输线理论,通过加载变容二极管的方式来实现天线工作频率的实时可调节。设计出的天线尺寸仅有15 mm×15 mm×0.8 mm,仿真结果表明：其工作频率可在S波段超过700 MHz的频率范围内可调。该天线具有结构简单、体积小等优点,具有一定的理论意义和广阔的应用前景。

英文摘要：

With the development of wireless communication system,antenna size and working flexibility attract scientific workers＇ widely attention,but the existing designs have the shortcomings of large size,complex reconfiguration method,and hardly to realize the frequency real-time tuned.Therefore,a frequency tunable antenna was designed.Based on the theory of Composite Right/Left Handed Transmission Line（CRLH TL）,varactor diode was loaded to realize the resonant frequency real-time tuned.The volume of the antenna was only 15 mm＊15 mm＊0.8 mm,simulation results showed that the resonant frequency could be tuned more than 700 MHz in S-band.The antenna had a simple structure,compact size,which had a certain theoretical value for further applications in microwave system.
