摘要

提出了利用具有三带陷波特性的m形带增强矩形单极超宽带天线的带宽。天线由带两个c型槽和一个倒u型槽的激励矩形贴片和带M型带的缺陷接地面组成。通过在矩形贴片上插入槽，可以得到三个陷波频带。基于所提出的矩形贴片天线的模拟阻抗，建立了一个概念模态来研究其三频带陷波特性。由VSWR < 2定义的天线模拟阻抗带宽为8.80 GHz，范围为3.35 GHz至12.15 GHz，其中WiMAX (3.53 - 3.98 GHz)、WLAN (5.16 - 5.80 GHz)和itu -频段(7.82 - 9.08GHz)分别有三个频段缺口。

Bandwidth enhancement of compact rectangular monopole UWB antenna using M-shaped strip with triple band notch characteristic

Bandwidth enhancement of a rectangular monopole UWB antenna using M-shaped strip with triple band notched characteristic is presented. Antenna consists of an exciting rectangular patch with two C-shaped and one inverted U-shaped slots along with defected ground plane which is coupled with M shaped strip. By inserting slots to the rectangular patch, three notched frequency bands are achieved. A conceptual modal, which is based on the simulated impedance of the proposed rectangular patch antenna, is also made to investigate the triple band notched characteristics. The simulated impedance bandwidth of antenna defined by VSWR < 2 is 8.80 GHz ranging from 3.35 GHz to 12.15 GHz with triple band notches first at WiMAX (3.53 – 3.98 GHz), second at WLAN (5.16 – 5.80 GHz) and third at ITU-band (7.82 – 9.08GHz).
