新型双陷波超宽带印刷天线的研究
Research on a Novel UWB Printed Antenna with Double Notches
采用共面波导(Coplanar-waveguide,CPW)馈电方式以及渐变斧头形缝隙，实现了超宽带(Ultra-wideband,UWB)天线。在该UWB天线的辐射贴片上刻蚀一个C形缝隙，并在渐变斧头形缝隙中加载支节谐振器，以抑制无线局域网（Wireless Local Area Network,WLAN)和全球微波互联网(Worldwide Interoperability for Microwave Access,WiMAX)频段对UWB系统的干扰，从而设计出了一种新型双陷波UWB天线。仿真和测量结果表明，该双陷波UWB天线的阻抗带宽为2.7～15.4GHz，在3.5 GHz和5.5 GHz处产生陷波，且在工作频段内具有良好的辐射方向图和稳定的增益。
novel ultra-wideband (UWB) antenna with double notches is proposed. The antenna is printed on FR-4 substrate with thickness of 0.4mm and fed by coplanar waveguide (CPW). The UWB characteristic of the antenna is achieved by etching an axe shaped slot on the patch. The double notches are realized by etching a C-slot on the patch and loading a stub resonator in the axe shaped slot, respectively, to avoid the interference of WLAN and WiMAX signals. The simulated and measured results show that the VSWR of the proposed antenna is less than 2 in a wide frequency range of 2.7 GHz~15.4 GHz with rejection at 3.5 GHz and 5.5 GHz. The antenna presents good radiation pattern and stable gain.
