提出了一种具有陷波及可重构特性的超宽带天线。天线采用在辐射贴片上引入开口圆环和在馈线上开倒U形槽的结构实现双陷波特性。采用在陷波结构中加入PIN二极管开关的方法实现陷波可重构特性
通过切换开关的断开与闭合
分别实现无陷波、单陷波和双陷波特性
进一步提高了超宽带频段的利用率。天线的体积仅为31 mm×24 mm×1.5 mm
结构紧凑。工作频带为2.8~3.2 GHz
4.0~5.0 GHz和6.0~12 GHz
实现了在3.2~4.0 GHz以及5.0~6.0 GHz两个频带的陷波特性
有效阻隔了WIMAX通信频段(3.3~3.6 GHz)、WLAN频段(5.150~5.285 GHz)的干扰。其他工作频段内
该天线具有较好的辐射特性
更适合应用在超宽带系统之中。
A kind of ultra wide band(UWB) antenna with band-notched and reconfigurable characteristics is proposed.The band-notched characteristics are achieved by introducing an open ring on the radiation patch and an inverted u-shaped slot on the feed line.Besides
the reconfigurable band-notched characteristics are realized by adding the PIN diodes switches on the band-notched structures.By controlling the switches on break and close
toggling among no band-notched
single band-notched and dual Band-Notched respectively
which greatly improves the utilization of ultra wideband frequency band.The antenna has a compact volume of 31 mm×24 mm×1.5 mm.The working frequency band of the antenna are 2.8~3.2 GHz
4.0~5.0 GHz and 6.0~12 GHz
it realizes band-notched characteristics od dual stop-bands at 3.2~4.0 GHz and 5.0~6.0 GHz and effectively rejects the jamming from WIMAX(3.3~3.6 GHz) and WLAN(5.15-5.825 GHz)communication frequency band.The antenna exhibits good radiation characteristics on the other working band
making it more suitable for UWB application.
