本文利用基于两层双共轭梯度-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24×31.7×1.6mm~3。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S_n<-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。
A novel broadband microstrip monopole antenna with low profile characteristic and a size of 24 × 31.7 × 1.6mm ~ 3 is studied by using the method of moment based on two layers of bi-conjugate gradient-fast Fourier transform. The designed antenna has broadband characteristics and the reflection coefficient S_n <-10dB between 3.1 GHz and 11 GHz. The antenna design steps and test results are discussed in detail. The results show that the antenna can be used for breast cancer imaging.
