无线通信的发展对天线(尤其是贴片天线)的各项性能提出了新的要求。与此同时，双频天线的应用也愈为广泛。总结了贴片天线的主要双频解决方案，包括正交模、多贴片、电抗性加载以及空气缝隙双频贴片等方式，并提出了相应双频贴片天线的适用场合。最后，结合HFSS仿真设计了一个双频双贴片天线，讨论了该天线特性，并对双频天线未来的发展趋势进行了展望。

With the development of wireless communication, some new performance requirements on the antennas have emerged. The applications of dual frequency antennas are more and more popular new. Some solutions to attain dual frequency operation of patch antennas are reported in this paper, such as Orthogonal mode, Multi patch, Reactively loading and some others. With HFSS simulating, one dual frequency antenna with two patches is designed. The development trend of dual frequency patch antennas is also discussed.
