摘　　要：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。This paper presents a flexible planar antenna in wireless local area network( WLAN) frequencies. The polyimide film with the thickness of 127μm was utilized as the substrate of the antenna. The dual band flexible antenna comprises the structure of the capacitive loaded monopole antenna. The whole antenna was coated with parylene-C film with the thickness of 10μm,which makes the antenna have good moisture-proof and waterproof performance. The characteristics of the presented antenna were measured under the conditions of planar and several kinds of bent conditions. The measured return loss of the antenna is better than 10 d B in the operating band and the antenna has the capability of omnidirectional radiation.The measured results showed that the antenna is suitable for integration with flexible electronic communication equipment.
