摘　　要：以传统矩形微带天线为基础模型,设计了一种双陷波超宽带阵列天线。阵列由两个相同结构的超宽带单极子天线构成,均由微带线馈电。通过在辐射贴片上蚀刻两个C型槽实现了WiMAX和WLAN频段的陷波,在两个贴片边缘开一个矩形缺口并加载寄生单元来提高隔离度。测试与仿真吻合度较好,天线覆盖2.5~12.0 GHz,具有3.3~3.7 GHz和5.1~5.9 GHz两个阻带,隔离度全部高于22 dB,峰值增益达6.7 dB,辐射方向近乎全向,可应用于UWB无线通信系统。Based on the traditional rectangular microstrip antenna,an ultra-wideband array antenna with dual band-notched was designed. The array consists of two ultra-wideband mono-pole antennas with same structure,all fed by microstrip line. The notchs in the Wi MAX and WLAN bands are realized by etching two C-shaped slots on the radiation patch. The isolation is improved by making rectangular notch at the edge of two patches and loading parasitic unit. The agreement between test and simulation is good. The antenna covers 2.5~12.0 GHz,which has two stop bands of 3.3~3.7 GHz and 5.1~5.9 GHz. The isolation is all higher than 22 dB,the peak gain is up to 6.7 dB and the radiation direction is nearly omnidirectional. The antenna can be used in UWB wireless communication systems.
