摘要:
在一款新型平面超宽带天线的基础上，通过在辐射贴片上开一个环形槽、在接地板上开一对对称的弯槽，实现了3.7~3.9 GHz和5~5.9 GHz的双陷波特性，有效地抑制了卫星C波段和无线局域网频段的信号对超宽带系统的干扰。对天线的陷波特性及原理进行了分析，并对所设计的天线进行了实物加工和测试，最后研究了天线的方向图和增益特性。结果显示，该天线性能优良，结构简单，易于集成，具有较高的应用价值。The proposed antenna achieved 3.7 - 3.9 GHz and 5 - 5.9 GHz dual band-notched characteristics with opening an annular slot on the radiating patch and etching a pair of symmetrical curved slot on the ground on the basis of a new planar ultra-wideband antenna, which effectively suppressed the interference of the satellite C-band and wireless LAN frequency band signal on UWB system. The notch characteristics and principle of the antenna were analyzed. The designed antenna were given physical processing and tested. Finally, the antenna radiation pattern and gain characteristics were studied. The results show that the antenna has high application value with excellent perfor- mance, simple structure and easy integration.
