【摘要】 本文提出了一种简洁的共形宽带圆极化(CP)缝隙天线,天线由单层介质基板两侧的矩形馈电贴片和具有C形辐射缝隙的接地板构成。在C形缝隙边缘处蚀刻成阶梯状,有效的拓宽了天线的3d B轴比带宽。设计的天线共形在半径50 mm的圆柱形载体上,仿真结果显示,天线的阻抗带宽和轴比带宽分别为43%(1.68-2.6 GHz)和59%(1.74-3.2 GHz)。更多还原

【Abstract】 In this paper, a compact conformal broadband circularly polarized(CP) slot antenna is proposed. The antenna consists of a rectangular feed patch and a ground plane with C-shaped radiated slot which are arranged at two-sides of a single-layer substrate. The stepped shape is etched at the edge of the C-shaped slot, which effectively broadens the 3 dB axial ratio band of the antenna. The designed antenna is conformal on a cylindrical carrier with a radius of 50 mm. The simulation results show that the impedance bandwidth and axial ratio bandwidth of the antenna are 43%(1.68-2.6 GHz) and 59%(1.74-3.2 GHz) respectively.更多还原
