Patent ID: 7446719

Claim:
A mobile antenna mounted on an electrically conductive body of a vehicle, in which the body of the vehicle has a first support portion extending substantially parallel to the around on which the vehicle is to be disposed, a second support portion extending substantially orthogonal to the ground, a corner portion at which the first support portion and the second support portion meet, the first support portion, the second support portion, and the corner portion support at least corner portion of a window of the vehicle, the mobile antenna comprising an electrically conductive antenna element having a first portion with one end and the other end extending therefrom, the one end of the first portion being arranged at least adjacent to any one of the first support portion, the second support portion, and the corner portion and being electrically connected to a feeding point, the other end of the first portion being arranged along a surface of the window such that polarized surfaces formed by the antenna element are non-orthogonal to a polarized surface of each of a vertically polarized wave and a horizontally polarized wave in radio waves, wherein the first support portion is a roof portion of the vehicle body, and the second support portion is a pillar portion of the vehicle body.
