【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 ultra-broadband antenna with three-notch characteristics is designed. The antenna is fed by gradual microstrip line, and ultra-broadband is realized by rectangular plus semicircular radiation unit and semicircular floor. The notch characteristics of WLAN/WiMAX are realized by etching symmetric L-shaped grooves and circular grooves on the radiation element, and the notch characteristics of X-band are achieved by adding symmetrical C-shaped resonators on both sides of the gradual microstrip feeder. The experimental results show that the voltage standing wave ratio of the antenna in 2.68~13GHz band is less than 2, and at the same time, the antenna has notch suppression in the frequency band of 3.1 卤3.8GHz, 5 鈮，
