The paper analyzed an s - band single ridged waveguide antenna used for near field measure by fdtd method and microwave transmition line theory 本文采用fdtd方法以及微波傳輸線理論對一個(gè)用于近場測量、工作在s波段的單脊波導(dǎo)天線進(jìn)行了分析。
Reference [ 1 ] has used the fdtd to solve some ridged waveguide and waveguide antenna to obtain the inside field . the feature of the paper is to analyze the antenna ' s near field in the rubber absorbing materials 文獻(xiàn)[ 1 ]等已對一些脊波導(dǎo)進(jìn)行過fdtd的數(shù)值解以求得到脊波導(dǎo)的內(nèi)場,本文的特點(diǎn)在于分析了s波段的脊波導(dǎo)天線在被測量的橡膠吸收材料中的輻射近場。
But ridged waveguide antenna which is small in volume when working at a low frequency band can obtain a high resolution and is suitable in the rubber material measure . one of the features of the paper is that some improvements of fdtd are presented 脊波導(dǎo)天線與普通金屬波導(dǎo)相比,在較低的頻域可以有較小的工作尺寸,因而能達(dá)到較高的分辨率,且便于與同軸饋線連接,很適合用于橡膠吸收材料的測量中。
