本論文分別提出可操作於GNSS及INMARSAT系統頻帶的寬頻與雙頻圓極化印刷單極天線設計,以及一個提高圓極化天線增益的金屬背腔設計。本文藉由幾個簡單的設計步驟,可將原來不具有圓極化特性的單極天線,逐步發展成圓極化頻寬大於35.2%的單極天線設計,同時天線還具有尺寸縮小化之效果。
另外,建立在本文所提出之寬頻圓極化單極天線的設計基礎上,我們也發展兩種具有頻比調控性之雙頻圓極化印刷單極天線設計,分別利用band-notch與拉開高頻圓極化頻帶的機制,來使得原來的寬頻圓極化頻帶逐漸分裂為雙頻,進而達成低頻比與高頻比之雙頻天線設計目標。
最後,為了提高天線增益,本論文在原先單極天線的下方加入一個具有金屬邊牆的金屬背腔,透過此背腔,我們可抑制天線背向輻射波達20 dB以上,同時增益可大幅提升約6 dBic的輻射特性。
This thesis presents a broadband and a dual-band circularly polarized (CP) printed monopole antenna design for GNSS and INMARSAT systems, as well as a back cavity design which is used to improve the antenna gain. Through a few simple design steps starting from a basic monopole antenna which does not have circular polarization characteristics originally, the designed CP monopole antenna having a small radiator size can achieve a 3-dB axial-ratio bandwidth more than 35.2%.
In addition, on the basis of the broadband CP monopole antenna mentioned above, we have also developed two dual-band CP monopole antennas with their dual-band frequency ratios controllable. For the antenna with its two CP bands created using a band-notch mechanism, the achieved dual-band frequency ratio is low. For the other with its two CP bands created by moving the upper portion of the wide CP band toward a higher frequency, the resulting dual-band frequency ratio is slightly higher.
Finally, in order to improve the antenna gain, we put a back cavity with metal sidewalls behind the monopole antennas. It can not only reduce the backward radiation by more than 20 dB but also increase the antenna gain by more than 6 dBic.
