Abstract
An antenna element is mounted on a glass of a rear quarter window of a vehicle along the edge thereof. A coupling element is provided midway along said antenna element for coupling between two segmented elements with phase adjustment between reception signals thereof in a specific frequency range. The coupling element connects the two segmented elements in lower frequency range, and disconnects the two elements in higher frequency range. The length of the antenna element is automatically corrected in respective low and high frequency ranges so as to cover a wide range.
