摘要

提出了一种双带陷波超宽带天线，具有可切换的5个陷波阻带。通过在馈线上加载带辐射贴片的改进t形环槽，实现了预测阻抗带宽3.2 ~ 15 GHz，双陷波带5.47 ~ 6.15和7.88 ~ 12 GHz。此外，在不同位置的改进t形环形槽上采用4个二极管，使天线在5个陷波带上可切换。对辐射方向图和增益进行了分析，并给出了结果。

Dual band-notched circular disc monopole UWB antenna with switchable five notched stop bands

A dual band-notched UWB antenna with switchable five notched stop bands is presented. Predicated impedance bandwidth 3.2–15 GHz with dual notched stop bands 5.47–6.15 and 7.88–12 GHz are achieved by loading a modified T-shaped ring slot on the feed line with radiating patch. Furthermore, four diodes are employed on modified T-shaped ring slot on different locations to make antenna switchable at five notched bands. The radiation pattern and gain is analyzed and results presented.
