| 摘 要： | 设计了一种紧凑的具有三陷波特性的超宽带天线。天线采用渐变微带线馈电,并通过矩形加半圆的辐射单元和半圆形地板来实现超宽带。通过在辐射单元上刻蚀对称的L形槽和圆环形槽,来实现在WLAN/WiMAX的陷波特性;在渐变微带馈线两侧增加对称的C形谐振器来达到在X频段的陷波特性。实验结果表明,天线在2.68~13GHz频段内电压驻波比小于2,同时在3.1~3.8GHz,5~5.9GHz,7.25~7.85GHz频段内有陷波抑制作用,且具有良好的辐射特性。天线具有较小的几何尺寸,仅为20mm×30mm。

| Abstract: | A compact UWB antenna with triple band notched feature is designed in this paper. The antenna consists of a rectangular radiating patch with a half circle at bottom, a tapered microstrip feed line, and a semielliptical ground plane. With a symmetrical L shaped slots and circular grooves etched on the radiating elements, the band notched characteristics of WLAN/WiMAX are created.The experimental results show that the voltage standing wave ratio (VSWR) of the designed antenna is less than 2 at the operating band from 2.68 GHz to 13 GHz;meanwhile,the notch suppression is realized at the operating band from 3.1 GHz to 3.8 GHz, 5 to 5.9 GHz, 7.25 to 7.85 GHz and good radiation patterns within the operating band have been observed. The antenna has compact size of only 20 mm×30 mm. |
