中文摘要 | In this paper, a broadband circularly-polarized (CP) L-shape planar metal antenna was designed and fabricated. The axial ratio of the radiated wave is found to be dependent of ratio of two segment of the physical L-shape metal strip. A wide bandwidth with good circular polarization (CP) radiation is more than 25%. Details of the proposed antenna design and the experimental results obtained for a fabricated prototype are presented. |
英文摘要 | 本文提出圓形極化之L形平面金屬天線的設計與製作,饋入金屬片與激發圓形極化幅射金屬片一體成型將簡化天線的製作。本項天線採用的0.1 mm 厚度金屬片,長度約半波長加以摺彎,金屬片其中之一角做截角,並將此天線置放於接地平面而中間介質為厚的空氣層(以提高圓形極化的頻寬),良好的圓形極化寬頻寬可達到25%。本項天線設計與實驗結果在本文中詳細地說明,依此說明得以完成天線成品的製作。 |
