摘要

本文介绍了一种用于无线应用的小型印刷单极天线的软件设计和改进。所提出的设计具有一个旋转的新月形贴片，该贴片由两个圆构成，并通过具有双馈电结构的微带线馈电。该结构建立在相对介电常数为4.4的FR4衬底上，具有57 × 37.5 mm2的表面积，以支持天线的增益、辐射效率等参数。本设计采用Ansoft HFSS13软件进行仿真。该设计提供1.98 GHz和3.76 GHz两种谐振，峰值增益分别为2.71 dB和2.18 dB。仿真结果表明，S11<-10 dB处的阻抗带宽为3.02 GHz(超过1.76-4.78 GHz)，可用于WLAN、WIMAX等移动应用。

Wideband Printed Monopole Antenna using Dual Feeding Structure for Wireless Applications

This paper presents software based design and enhancement of a compact printed monopole antenna for wireless applications. The presented design has a rotated crescent shaped patch which is constructed using two circles and fed through a microstrip line with a dual fed structure. The structure is built on FR4 substrate which has relative permittivity of 4.4 having 57 × 37.5 mm2 surface areas to support the gain, radiation efficiency and other parameters of the antenna. The design is simulated using Ansoft HFSS13. This design offers two resonances at 1.98 GHz and 3.76 GHz with respective peak gains of 2.71 dB and 2.18 dB. The simulated result shows that the impedance bandwidth at S11<-10 dB is 3.02 GHz (over 1.76-4.78 GHz) can therefore be used for WLAN, WIMAX and other mobile applications.
