本論文提出應用於可摺疊手機之多輸入多輸出天線設計，兩款皆參考市售摺疊手機之環境所設計而成，其天線設計涵蓋範圍LTE / WWAN / WLAN及Sub-6 GHz操作頻段，利用槽孔天線、倒F型天線以及單極天線搭配匹配電路設計來達成所需頻段。
　　第一款天線為應用於摺疊手機之天線增益疊加設計，整體結構以槽孔天線結合匹配電路做設計，並利用手機摺疊後，將接地面當成反射板，疊加天線本身之直射波以增加其輻射強度，使呈現提高增益的特性，增益可提高2 dB。第二款為提出一款窄邊框全屏幕摺疊手機之多輸入多輸出天線設計，運用IFA天線及耦合線饋入方式，再整合匹配網路設計來完成所需頻段。

In this thesis, two MIMO antenna designs applied in the folding mobile phone have been proposed, which design for the commercial. Those antennas are designed for LTE, WLAN, and Sub-6 GHz bands. Antennas' design by slot, inverted-F, and monopole.
The first antenna is designed to improve antenna gain in folding mobile phones. This antenna's structure design by slot and matching network. In folded mode, the ground plane is regarded as a reflective plate to improve the antenna's directivity. Gain can be improve by 2 dB in folded mode.
The second design is regarded with MIMO antennas for narrow-frame full-screen in folding mobile phone. The antenna using an inverted-F, and coupling feed-in line structure, those strategies can achieve the required frequency band with integrated matching network design.
