應用於微波滅病毒裝置之寬頻高增益微帶塊狀天線之設計

本論文提出一種設計寬頻帶槽孔耦合饋入之微帶天線的方法。藉由偏離槽孔饋入位置的方法，在微帶天線的共振邊上產生一個虛擬的開路邊界條件，得到一個額外的共振模態，而產生寬頻帶的特性。此外，也利用此概念為基礎設計了一個寬頻的微帶天線陣列，之後，將所設計的微帶天線陣列和一個現有的功率放大器模組整合成一個系統並且量測該系統所輻射的功率密度特性，最後，該系統會被當作微波病毒殺蟲劑來消滅H1N1病毒。所有的設計皆經過實驗量測和模擬的驗證，相關的實驗配置與結果在文中也將會有詳細的探討。

A concept for designing a broadband aperture-coupled microstrip patch antenna is presented in this thesis. The proposed patch antenna is fed by a coupling aperture, offset from the patch center. This generates a fictitious open circuit within the resonating edges of the patch, and therefore, an additional resonant frequency is produced and a wide impedance bandwidth can be obtained. Also, a broadband patch array using the patch as its radiating elements is presented. All the designs are fabricated and verified via both measurements and simulations. Then, the proposed patch array is integrated with an off-the-shelf power amplifier module, and the power density radiated by the system is further characterized. Finally, this system is used as a microwave virus sanitizer to eliminate the H1N1 viruses, and a series of experiments is setup and performed. The associated results are also presented.
