摘要 MIMO天線包括兩個可重新配置的印刷單極天線與耦合導體和隔離改進 為了改變工作頻率，PIN二極管被嵌入天線 根據PIN二極管的通/斷狀態，諧振頻率在WLAN頻帶之間改變（2400-2483MHz和5150-5350MHz）和m的WiMAX頻帶（3400-3600MHz）

天線結構 天線整體尺寸:80x40mm2 天線輻射尺寸:15x40mm2 應用頻帶: WLAN (2400–2483 MHz,5150–5350MHz) m-WiMAX (3400–3600 MHz)

正面

反面

根據二極管開關狀態模擬

L5參數探討

2.4GHz的電流分布圖

L9參數探討

模擬測量S11和S21

結論 MIMO天線提出了高隔離度 一個IIS來放置天線之間高隔離在所有工作頻帶實現低於220 dB的隔離值 多樣性表現由ECC和MEG率評估，並表現出優異的值

心得 這次的paper跟上一篇難易度差距蠻大的，內容都看不太懂，多了許多陌生的東西像是隔離，隔離對MIMO來說好像是必要的，所以要好好的學起來。
