PURPOSE: To provide a car antenna structure on the front window in which FM and AM waves can be well received without loss of visibility. CONSTITUTION: This car antenna structure includes antenna elements for receiving FM and AM waves that are installed on the front window(FW) by either the printing or the sealing process. The antenna element 1, which is in a loop shape (for instance an inverted convex shape), is arranged near upper edge of the front window. The antenna element 2 which is connected with the bottom edge of the loop of antenna 1 in direct current is extended vertically down toward the lower edge of the front window along the center in the width. In this structure there is also a feeding point P that is installed on the upper part of the loop of antenna element 1 and the silver paste containing dark colored carbon particles is adopted as a material of the antenna elements 1 and 2.
