Vehicle antenna device

Abstract

A vehicle antenna device includes a plate-like element and a ground substrate. The plate-like element has a feed part and a leading end part extending a predetermined line width from the feed part to the leading end part to define a blank part at its center as viewed from above. The plate-like element has an open part extending from the blank part between the feed part and the leading end to transmit and receive signals of a predetermined frequency band. The ground substrate has a ground part serving as a ground of the plate-like element and a feed point connected with the feed part of the plate-like element and is disposed such that a large part of the ground part does not overlap the plate-like element as viewed from above and does not run off the range defined by the blank part and the open part.
