Abstract
A vehicular antenna is mounted on a circuit board in a monitor. The circuit board has a conductor substrate that is used as a ground for the antenna, and it has a frame shape that has a rectangular inner edge. The circuit board has an electrical contact for connecting the antenna. The electrical contact is placed at λ/4 away from an axisymmetrical line (center line) with respect to the inner edge. As a result, a gain of the vehicular antenna is not reduced in a front direction even when the vehicular antenna uses the frame shape conductor as the ground.
