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 脊波导天线与普通金属波导相比，在较低的频域可以有较小的工作尺寸，因而能达到较高的分辨率，且便于与同轴馈线连接，很适合用于橡胶吸收材料的测量中。
