摘要(中) 本論文主要提出一種新型結構,製作在單一層面的金屬介質基板RF4板材上。首先以單頻共平面波導槽孔天線做研習,之後設計出具有寬頻圓極化共平面波導(CPW)饋入槽孔天線。利用接地金屬環狀不對稱,使其電流分佈能激發出相鄰共振模態產生寬頻帶作用,在接地金屬環狀左內側彎沿出C形殘段,提供另一電流路徑使電場能有正交、等振幅以及90°相位差,在遠場輻射圓極化波,在接地金屬環狀右下角落嵌入一C形槽孔,以改善3-dB軸比頻帶寬度及10-dB阻抗頻寬。天線主體包含有共平面波導饋入線、輻射金屬貼片、非對稱接地金屬貼片、C形殘段及槽孔結構。量測結果,天線10-dB阻抗頻寬(VSWR 2)有0.92 GHz (46% 1.33-2.25 GHz), 3-dB軸比(AR)頻寬有0.65 GHz (32.5% 1.55-2.2 GHz),最大增益為 3.31 dBi變化範圍在1 dBi內,適合一般無線通訊產品(1.71-2.17 GHz)及導航系統(1.57-1.61 GHz)。
摘要(英) This thesis describes the design with simplification structure and fabrication on the same plane of FR-4 substrate. At first studying the single band CPW-fed slot antenna, and then designing of proposed broadband circular polarization CPW-fed slot antenna, which is achieved by an asymmetry ground plane makes the adjacent resonant mode to merge into a wide operation bandwidth and etching C-shaped ground strip on the edge of left side of ground plane to offer the current path, two orthogonal electric fields with a 90°phase difference for exciting a circular polarization radiation wave. On the other hand, a C-shaped slot is embedded at the bottom right corner of ground plane. It is used for broadband AR and impedance matching. The measured impedance bandwidth (VSWR 2) is 0.92 GHz (46% relative to the center frequency at 2 GHz). The 3-dB axial ratio bandwidth (ARBW) is 0.65 GHz (32.5% relative to the center frequency at 2 GHz), and antenna peak gain is 3.31 dBi with variations of less than 1 dBi. This antenna is suitable for wireless communication system (1.71-2.17 GHz) and navigation system (1.57-1.61 GHz).
