摘要

提出了一种新型超宽带(UWB)方向分集天线设计方案，并给出了仿真结果。该天线结构尺寸为40×42×21 mm3，由圆盘辐射元件组成，由两条同轴线以90°角在两点馈电。馈线的激励决定了天线的辐射方向图，该方向图是定向的或斜视的。所述圆盘及其馈线由形如空腔的接平面支撑。磁盘的几何形状也略有修改，以抑制不必要的辐射和增加端口隔离。天线阻抗带宽在6.8 GHz到15ghz以上。

Ultra-wideband pattern diversity antenna with cavity

A new ultra-wideband (UWB) pattern diversity antenna design is proposed and simulation results are presented. With a size 40×42×21 mm3, the proposed antenna structure consists of a disk radiating element, fed at two points at 90° angle by two coaxial lines. The excitation of feed lines determines the radiation pattern of the antenna, which is either directional or squinted. The disk and its feed lines are supported by a ground plane which is shaped like a cavity. The disks are also slightly modified in geometry to suppress unwanted radiation and increase ports isolation. The antenna shows an impedance bandwidth from 6.8 GHz to more than 15 GHz.
