摘要

A narrowcast broadcasting with a part of the terrestrial digital broadcasting is proposed and developed. To perform stable reception of the broadcasting, a planar antenna with a high gain and a nondirectional characteristic is necessary on the roof of the vehicle. In this paper, it is clarified that the proposed antenna has the excellent reception characteristics, compared with the commercialized antenna. Also, it is clarified that the narrowcast broadcasting with the part of 22ch is received almost perfectly within the area of TSB Zenkoujidaira broadcasting relay station.
