The hexagon fractional slot structure is chosen, the gradually changed CPW feed is adopted. Not only the bandwidth of matched impedance is expanded, but also the antenna's miniaturization is realized.
选择正六边形分形缝隙结构，采用渐变的共面波导馈电，不仅拓宽了阻抗带宽，而且实现了天线的小型化。
Two kinds of SAWF using respectively usual and SPUDT tapered transducers with 15% fractional bandwidth are designed on Y128. One transducer is block weighted, and the other one withdrawal - weighted.
我们在Y128基片上采用一般型和SPUDT型锥型换能器制作了相对带宽约15%的声表面波滤波器，一个换能器采用“块加权”，另一个换能器采用抽指加权。
In this article some results about the study of a SAW power series fm-dl (pfm-dl) with time-bandwidth product of 160 and fractional bandwidth of 32% are presented.
