Abstract

Two types of wide-band electromagnetic wave absorber panel were developed for multipath interference reduction in urban communication systems. The characteristics were measured using mock-ups of the absorber panel with the time domain method. In this paper, an application of the developed absorber panel to digital television broadcasting and the influence of the difference between an actual absorber panel and mock-up on its performance are discussed. It is estimated that the area of communication disturbance is eliminated by applying the developed absorber panel. By experiments, it became clear that the several factors reduce the frequency range in which the reflection is suppressed below -14dB.
