本論文提出應用於5G手機之雙極化槽孔天線設計，並以槽孔天線與開環諧振器(SRR)為主要研究目標，提出應用於為5G N78(3300 MHz~3800 MHz)的頻帶的雙極化槽孔天線設計，並在槽孔天線的上方加入開槽環形諧振器(SRR)，使得槽孔上方兩個饋入的隔離度提升4 dB以上，並探討開槽環形諧振器(SRR)對於槽孔天線的影響，且設計不同的饋入方式討論其中的區別以及對天線特性的影響。

This paper proposes the design of a dual-polarizedslot antenna applied to 5G mobile phones, takes the slot antenna and split-ringresonator (SRR) as the main research objectives, and proposes a design for thefrequency band of 5G N78 (3300 MHz~3800 MHz). The dual-polarized slot antennadesign, a slotted ring resonator (SRR) is added above the slot antenna, so thatthe isolation of the two feeds above the slot is increased by more than 4 dB,the slotted ring resonator (SRR) is discussed on the slot antenna, designdifferent feeding methods to discuss the difference and the influence on theantenna characteristics.
