摘要

提出了一种在WiMAX和WLAN通信链路上具有双陷波特性的紧凑型缝隙超宽带(UWB)天线。该天线具有改进的矩形辐射贴片，并在50Ω微带馈线附近倾斜。WiMAX和WLAN的带阻滤波是通过在有缺陷的接地结构中刻蚀一个矩形槽和在改进的金属贴片中刻蚀一个c形槽来实现的。通过与其他引用的参考天线的比较，所提出的天线设计的新颖性是实现了总体尺寸减小的双陷口。模拟的群延迟和峰值增益均在超宽带要求范围内。VSWR的模拟结果与实测结果吻合良好(<;2)和二维辐射方向图(全向)证明该天线可能适用于覆盖3.1至10.6 GHz频率范围的超宽带应用。两个陷波避免了与其他窄带无线通信系统的干扰问题。

A compact UWB antenna with dual band-notched at WiMAX and WLAN for UWB applications

A compact slot Ultra Wide Band (UWB) antenna with dual band-notched characteristics at WiMAX and WLAN communication links is proposed. The proposed antenna has modified rectangular radiating patch and is beveled near the 50Ω microstrip feed-line. The band-stop filtering at WiMAX and WLAN is achieved by etching a rectangular-slot in the defective ground structure and a C-shaped slot in the modified metal patch. The novelty of the proposed antenna design is achievement of dual notches with reduced overall size as shown through comparison with other quoted reference antennas. The simulated group delay and peak gain are within UWB requirements. Good agreement between the simulated and measured results for VSWR (<; 2) and 2-D radiation patterns (omnidirectional) proves that this antenna may be suitable for UWB applications covering frequency range from 3.1 to 10.6 GHz. The two band-notches avoid the interference problem with other narrowband wireless communication systems.
