本論文提出一種應用於100 GHz頻段之雙極化貼片天線陣列設計。設計中選用貼片天線作為陣列單元，採用槽孔耦合方式進行饋入，以實現10%比例頻寬之雙極化特性。為進一步優化陣列元素的輻射場型，於陣列周圍引入虛擬（dummy）天線，比較配置有無dummy天線時天線陣列之性能差異，並於後續設計功率分配器於天線陣列中。 本論文中天線之設計是使用國家研究院台灣半導體研究中心（Taiwan Semiconductor Research Institute, TSRI）提供之印刷電路基板製程。天線陣列元素量測結果之阻抗頻寬分別X極化為95.81-104.35 GHz，在100 GHz增益為3.63 dBi，Y極化為94.02-103.51 GHz，在100 GHz增益為3.48 dBi；天線陣列量測結果之阻抗頻寬分別X極化為94.04-104.41 GHz，在100 GHz增益為8.68 dBi，Y極化之阻抗頻寬為96.36-99.75 GHz、104.18-106.24 GHz，在100 GHz增益為8.88 dBi。 ;This thesis proposes a design of dual-polarized patch antenna array operating at 100 GHz. In the design, patch antennas are employed as array elements, and a slot-coupled feeding method is utilized to achieve 10% fractional bandwidth for dual-polarization operation. To further enhance the radiation patterns of the array elements, dummy antennas are deployed around the periphery of the array. The performance differences of antenna arrays with and without dummy elements are compared. In addition, power dividers have been designed for the antenna array. The antenna design in the thesis uses the printed circuit board substrate fabrication provided by the Taiwan Semiconductor Research Institute (TSRI). The measured impedance bandwidth of the array element for x-polarization ranges from 95.81 to 104.35 GHz, with the gain of 3.63 dBi at 100 GHz. For y-polarization, measured impedance bandwidth ranges from 94.02 to 103.51 GHz, with gain of the 3.04 dBi at 100 GHz The measured impedance bandwidth of the antenna array for x-polarization ranges from 94.04 to 104.41 GHz, with the gain of 8.68 dBi at 100 GHz. For y-polarization, the impedance bandwidths are from 96.36 to 99.75 GHz and 104.18 to 106.24 GHz, with the gain of 8.88 dBi at 100 GHz.
