中文摘要 | 本論文之重點在於X頻段雷達天線設計及特性探討;現今大型雷達網對於單兵、戰鬥車輛、微飛行器或小型船艦等,仍欠缺有效率的戰場偵蒐裝備。探討製造結構簡單的天線,在應用雷達系統方面可提出來做研究,其輻射場型是非常集中之波束,而且指向性很高,其場型特性走向電流性的極性輻射,且實驗的結果可以完全結合理論,使用高頻結構模擬軟體工具,大家可以設計與建立整個天線以及其單一基板所注入之系統。優點有尺寸小、低旁瓣與低成本等,可以展現出一個X頻段之縫隙陣列天線整個設計與實驗成果。輻射波導縫隙陣列天線持續研究,就好比其有低旁瓣、重量輕與結構簡單但有效率,容易去建立有效成本設計天線類型,並可以圓滿成功量測實驗結果。 |
英文摘要 | This paper is mainly aimed at the X-band standing-wave slot array radar antenna design and characteristics. Today, the large-scale radar network for the individual-soldier, combat-vehicles, micro-aircraft or small-ship is still with lack of effective battlefield reconnaissance equipment. A new antenna structure, simple and suitable for mass production, is proposed in this study to be applied to radar systems. The radiation patterns are the shape of conical beam and its directivity is high. The polarization characteristics are investigated to enable the circularly polarized radiation, and the experimental results fit well with theory. With a commercial simulation tool, HFSS (High Frequency Structure Software) from Ansoft, we designed and fabricated the whole antenna and its feeding system on a single substrate, taking advantages of small size, low profile, and low cost, etc.—the design process and experimental results of a line slot array antenna at X-band are presented. The RWSA (Radial Waveguide Slot Array) antenna is investigated as a low profile, lightly weight, simple but effective, easy to design and fabricate with reasonable cost efficiency with a prototype of the antenna designed, fabricated and successfully tested. |
