设计了一种用于无线局域网(WLAN)的平面柔性天线。该天线的设计采用厚度为127μm的聚酰亚胺薄膜作为天线的印制板,利用电容加载的单极子天线结构,使其获得了柔性和双频宽带的性能。整个天线被10μm厚度的Parylene-C保护涂层所覆盖,使天线具备了良好的防潮、防水等性能。对天线在平面和各种弯曲状态下的性能进行了测试,测试结果表明,该天线在工作频带内的回波损耗优于10d B,具有较好的全向辐射特性,实验结果表明该天线可以应用于柔性通信设备中。
A planar flexible antenna for wireless local area network (WLAN) is designed. The design of the antenna uses a polyimide film with a thickness of 127μm as the printed circuit board of the antenna, and utilizes the capacitance loaded monopole antenna structure to obtain the flexible and dual-band broadband performance. The entire antenna is covered by a 10μm Parylene-C protective coating, giving the antenna a good moisture and water resistance. The test results show that the antenna has better return loss in the working frequency band than 10d B and has good omnidirectional radiation characteristics. The experimental results show that the antenna can Used in flexible communication equipment.
