摘要

提出了一种小型CPW馈电三带陷波(超宽带)超宽带天线。该天线由带有三个c形槽的铲形辐射贴片、馈线和改进的接地面组成。通过在辐射贴片上刻蚀3个可变尺寸的c型槽，产生频率带阻性能，通过修改c型槽的尺寸来控制其带陷波频率和带宽。所提出的天线尺寸非常紧凑，为14×22×1.6mm3。仿真结果表明，该天线除3.20 ~ 3.97GHz、5.26 ~ 5.75GHz和7.57 ~ 8.37 GHz外，在2.88 ~ 10.67 GHz范围内均能正常工作，驻波比均小于2。

A small UWB antenna with triple band-notched characteristics

A small CPW fed triple band-notched (Ultra Wide Band) UWB antenna is presented. The proposed antenna consists of a shovel-shaped radiating patch with three C-shaped slots, a feed line and a modified ground plane. By etching three C-shaped slots with variable dimensions on the radiating patch, frequency band-stop performance is generated and we can control its band-notched frequency and bandwidth through modifying the dimensions of C-shaped slot. The proposed antenna has a very compact size of 14×22×1.6mm3. Simulated VSWR shows that the proposed antenna could operate from 2.88 to 10.67 GHz with VSWR less than 2, except 3.20 to 3.97GHz, 5.26 to 5.75GHz and 7.57 to 8.37 GHz.
