摘要

针对超宽带(UWB)通信中UWB系统与基于IEEE 802.11a标准的无线局域网(wlan)之间的电磁干扰，提出了一种频率带陷波天线。该天线设计在尺寸为12×18 mm2，厚度为1.6 mm，相对介电常数(εr)为4.4的FR4衬底上，提供4.9 ~ 6.2 GHz的频率陷波。这种天线由印在圆形贴片上的矩形槽内的两条导电带组成。该天线提供4.4 ~ 11.2 GHz的宽带宽度，单频段陷波范围为4.9 ~ 6.2 GHz，以避免UWB频段与现有系统的干扰。利用HFSS对天线的设计参数和性能进行了分析。该天线具有良好的全向辐射方向图和增益。

Frequency notched antenna to overcome EMI between UWB systems and Wireless Local Area Networks (WLANs)

This paper presents frequency band-notched antenna to overcome electromagnetic interference (EMI) between UWB systems and Wireless Local Area Networks (WLANs) based on IEEE 802.11a standard for Ultra Wide-Band (UWB) communication. The proposed antenna is designed on FR4 substrate having a size of 12×18 mm2 with thickness of 1.6 mm and relative permittivity (εr) of 4.4 which provides frequency notching from 4.9 to 6.2 GHz. This antenna consists of two conducting strips inside a rectangular slot printed on circular shaped patch. This antenna provides a wide band width from 4.4 to 11.2 GHz with single band frequency notch from 4.9 to 6.2 GHz to avoid interference of UWB band with the existing systems. The design parameters and the performance of the proposed antenna are analyzed by using HFSS. The antenna displays a good omnidirectional radiation pattern and gain.
