摘要

本文的目的是设计和分析一种适用于无线应用的双宽带紧凑型天线。利用分形几何克服了微带贴片天线的局限性。天线设计半径为15mm,相对介电常数为4.4,损耗因子为0.025。测量结果表明,该天线具有1.84GHz (2.2GHz-4.07GHz)和2GHz (6GHz-8GHz)的双频段工作,回波损耗低于-10dB,可应用于无线局域网(WLAN)和超宽带应用。

Dual Band Fractal Antenna Design for Wireless Application
The objective of this paper was to design and analyze a dual wide band compact antenna for wireless application. Microstrip patch antenna limitation was overcome by using fractal geometry. The proposed antenna was designed with a radius of 15mm on a FR4 lossy substrate with relative permittivity of 4.4 and loss factor of 0.025. Measurement result showed that the antenna has a dual band of operation with bandwidth for return loss below -10dB of 1.84GHz (2.2GHz-4.07GHz) and 2GHz (6GHz-8GHz) which can be applied to wireless local area network (WLAN) and Ultra wide band applications.
