摘要/Abstract

摘要： 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 dB，其中最高隔离度达到30 dB.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.

关键词: 分集天线, 去耦合, 非对称共面带, 小型化, 高隔离

Abstract: 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 about 50%; 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.

Key words: diversity antenna, decoupling, asymmetric coplanar band, compact, high isolation
