摘要

We focus on a wave absorber using resistive film and soft ferrite board which made of magnetic material and realize wide angle characteristics to satisfy the specifications of DSRC (Dedicated Short Range Communication). First, we show designed chart to the combination of surface resistance of resistive film and thickness of soft ferrite board. Second, we actually fabricate the wave absorber based on the designed values. For straight polarized wave, the absorption of 30dB is obtained at 5.8GHz for the perpendicular incidence. The measured results of the angle characteristics in circularly polarized wave are satisfied with specifications of DSRC. The results show that the readability of the wave absorber for DSRC is shown when the thickness of the presented absorber is set to about 5.5mm.
