一款用于乳腺癌成像的低轮廓单极子天线设计

内容简介：本文利用基于两层双共轭梯度一快速傅立叶变换的矩量法研究了一种新颖的宽带微带单极天线,该天线具有低轮廓特性,尺寸为24×31.7×1.6 mm3.设计的天线具有宽带特性,在3.1 GHz到11 GHz之间的反射系数S11＜-10dB.详细探讨了上述天线的设计步骤和测试结果,结果证明该天线可以用于乳腺癌成像.

Abstract：In this paper,a novel wideband microstrip-fed monopole antenna with a size of only 24 mm×3 1.7 mm×1.6 mm is studied by the method of moment based on the two-level bi-conjugate gradient-fast Fourier transform method.The antenna has a wide bandwidth ranging from 3.1 GHz to 11 GHz for S11＜-10 dB (S11 denotes the return losses).Details of the proposed antenna design approach and measured results are presented and discussed,which can be used for Ultra-wideband applications in the area of breast cancer imaging.
