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. %U https://journal.bupt.edu.cn/EN/10.13190/j.jbupt.2018-245
