摘要

本文提出了一种用于无线局域网(WLAN)的双频单极天线。天线由带两个槽的矩形环和缺陷地平面组成，因此产生两种谐振模式，覆盖2.7 GHz和5.5 GHz WLAN频段。天线由50条Ω微带线馈电。天线的整体尺寸为20×25×0.8mm3设计的天线工作频率范围为2.1-2.84 GHz和5.1-5.89 GHz，回波损耗< - 10db，适合WLAN频段。利用天线的辐射方向图、峰值实现增益、辐射效率和电流分布分析了天线的辐射特性。该天线的辐射方向图是全向的。该天线在2.7 GHz频段峰值实现增益为2.00 dBi，在5.5 GHz频段峰值实现增益为3.25 dBi，辐射效率在2.7 GHz和5.5 GHz频段分别为90.29%和88.98%。

Design of monopole antenna with defected ground for WLAN application

In this paper, a dual-band monopole antenna is proposed for wireless local area network (WLAN) application. The antenna consists of rectangular ring with two slots and defected ground plane, due to which two resonant modes are generated to cover 2.7 and 5.5 GHz WLAN bands. The antenna is fed by 50 Ω microstrip lines. The overall dimension of the antenna is 20×25×0.8mm3 The designed antenna operates over the frequency ranges from 2.1-2.84 GHz and 5.1-5.89 GHz with <;-10 dB return loss which is suitable for WLAN bands. The Radiation pattern, peak realized gain, radiation efficiency and current distribution are used to analyze the radiation characteristics of the antenna. The radiation pattern of the proposed antenna is omnidirectional. The peak realized gain of the antenna is 2.00 dBi at 2.7 GHz band and 3.25 dBi at 5.5 GHz band and the radiation efficiency is 90.29% at 2.7 GHz band and 88.98% at 5.5 GHz band respectively.
