Abstract (en)
An antenna device includes a main antenna body having a patch antenna element; a feeder cable connected to and extending outward from the main antenna body; and a sheet-metal bracket which supports the main antenna body and is mounted to an installation base material, such as a dashboard. For example, the bracket has a shape of a rectangle. In order to increase the radiation gain at a low elevation angle in the cable-extending direction, the widthwise direction of the bracket is substantially aligned with the cable-extending direction. On the other hand, in order to reduce the radiation towards a back surface of the antenna device in a specific direction, the lengthwise direction of the bracket is substantially aligned with the cable-extending direction so that the lengthwise direction is aligned with this specific direction.
