摘　　要：提出了一种具有双陷波可重构特性的蓝牙/超宽带(UWB)天线。天线由削顶圆形单极子天线加载1/4波长圆弧枝节组成。在圆形贴片上刻蚀2个半波长圆形缝隙,实现WLAN(5.125~5.825 GHz)和ITU(8.025~8.4 GHz)频段的陷波功能。通过控制安装在陷波结构中PIN二极管的工作状态,能够实现陷波的可重构特性。测试与仿真结果表明:在天线工作频段2.39~2.52 GHz和2.92~12 GHz内,天线辐射性能良好,峰值增益达到5.2 dBi。可广泛应用在各种通信系统。An antenna for Bluetooth and ultra-wideband(UWB)applications with dual band-notch reconfigurable characteristics is proposed.The antenna consists of a truncated circular monopole antenna and a 1/4 wavelength circular branch.Two half-wavelength circular gaps are etched on the circular patch to achieve notch function in WLAN(5.125~5.825 GHz)and ITU(8.025~8.4 GHz)bands.The reconfigurable characteristics of band notch can be realized by controlling the working state of PIN diode installed in notch structure.The test and simulation results show that in antenna working frequency range of 2.39~2.52 GHz and 2.92~12 GHz,radiation performance of the antenna is good,and the peak gain reaches 5.2 dBi.It can be widely used in various communication systems.
