摘要
本文设计了一种结构较为简单的双陷波超宽带天线,其尺寸为32 mm×28 mm×0.508 mm,天线采用圆形辐射贴片,通过在地板上挖不同大小的矩形缺口的方法实现超宽带,达到了规定的3.1~10.6 GHz带宽要求;在圆形贴片上挖开一对变形的C形互补开口谐振环(CSRR),实现了天线在WiMAX(3.3~3.8 GHz)和WLAN(5.15~5.85 GHz)两个频段的陷波功能,除陷波频段外其他频段的VSWR值均小于2,且天线的辐射特性良好,能达到无线通信的要求。
In this paper,a simple double notch ultra-wideband antenna is designed with a size of 32 mm×28 mm×0.508 mm.The antenna adopts a circular radiation patch,which achieves ultra-wideband by digging rectangular gaps of different sizes on the floor,and reaches the prescribed band of 3.1-10.6 GHz.A pair of deformed c-shaped complementary split ring resonator(CSRR)were dug out on the circular patch to realize the functions of WiMAX(3.3-3.8 GHz)and WLAN(5.15-5.85 GHz)notch wave.The VSWR value of all frequency bands except the trap frequency band was less than 2,and the radiation characteristics of the antenna were good,which could meet the requirements of wireless communication.
