一种非对称馈电的小型化高隔离度分集天线

An Asymmetric Feed Compact High Isolation Diversity Antenna

提出一种基于非对称共面带(ACS)馈电的高隔离度小型化分集天线结构.使用ACS作为天线馈电结构可使天线体积减小约50%.引入地板延伸枝节作为去耦合结构,使天线间端口隔离度大于15 d B,其中最高隔离度达到30 d B.实验结果表明,该分集天线可满足2. 4/5. 2 GHz WLAN和2. 6/3. 5 GHz LTE的通信需求.

A high isolation compact diversity antenna structure based on asymmetric coplanar band(ACS)feed is proposed.Use of ACS as the antenna feed structure reduces the antenna volume by about50%;by introducing the floor extension branch as a decoupling structure,the high antenna port isolation is achieved to 15 dB and is highest to 30 dB.It is shown that the diversity antenna can satisfy the 2.4/5.2 GHz WLAN,2.6/3.5 GHz LTE communication requirements.
