摘要

提出了一种用于WiMAX和WLAN应用的新型双陷波带超宽带印刷单极天线。利用环形单极子的宽带特性，实现了S11< - 10dB时2.89GHz-12GHz的阻抗带宽。通过在锥形微带馈线中嵌入倒u型槽来创建两个陷波带，以最大限度地减少来自其他在3.3-3.6GHz和5.15-5.825GHz频段工作的无线通信系统的干扰。更重要的是，两个插槽具有弱互耦性，可以单独和随机调谐，并且可以很容易地设计出适合不同无线标准的陷波频率。此外，该天线的整体尺寸非常紧凑，为20mm × 16mm，在设计过程中获得了稳定的增益和方向图。

Ultrawide-band printed monopole antenna with dual notched bands for WiMAX and WLAN applications

A novel UWB printed monopole antenna with dual notched bands for WiMAX and WLAN applications is presented. The impedance bandwidth of 2.89GHz–12GHz with S11<−10dB is achieved based on the wideband property of the annular ring monopole. Two notched bands are created by embed inverted-U-slots in the tapered microstrip feed line for minimize the interference from other wireless communication systems operating in 3.3–3.6GHz and 5.15–5.825GHz bands. The more important point is that the two slots have weak mutual coupling to be tuned individually and randomly, and the notched frequencies can be easily designed to fit for the different wireless standards. Besides, the presented antenna has a very compact overall size of 20mm × 16mm, and stable gain and patterns are obtained during the design procedure.
