| dc.description.abstract | 本論文主旨為提出使用雙層印刷電路板實現之寬頻雙圓極化天線陣列，其方法為透過序列式旋轉技巧，搭配寬頻的線性極化天線作為輻射體及寬頻方向耦合器作為饋入網路來達成。
前半部旨在個別研究方向耦合器與方型槽孔天線。第一部分，吾人欲設計一架構簡單且易於整合之寬頻方向耦合器，提供兩能量相等且具有90°相位差之訊號。文中簡介方向耦合器基本理論並提出兩種方向耦合器之架構設計。第二部分，吾人將研究方型槽孔天線輻射原理並提出設計方法。 後半部則是整合方向耦合器與方型槽孔天線，並利用序列式旋轉技巧，完成一具寬頻雙圓極化特性的槽孔天線陣列。 | zh_TW |
| dc.description.abstract | A novel wideband dual-sense circularly polarized antenna array is presented is this thesis. The antenna array module consists of two rectangular aperture antennas of linearly polarized radiation and a directional coupler employed for the 90° phase feed in a sequential rotation scheme. First, we reviewed the directional coupler basic theory and proposed two coupler designs. Also, the design procedure was given, in terms of the design of the radiating elements using rectangular aperture antennas. Lastly we integrated the coupler and the antennas as a sequential rotation array. Both simulated and measured results were included, shows good consistency in this thesis. | en |
