This spoiler is attached to the rear end of the vehicle to improve the aerodynamic characteristics (aerodynamics) of the vehicle, and the so-called GPS (Global Positioning) inside the spoiler.
System) antenna is installed. The GPS antenna receives signals transmitted from a plurality of, for example, three artificial satellites at the same time, and thus is formed in a so-called omnidirectional manner with respect to the sky.

From this point of view, it may be considered to house an antenna for receiving satellite broadcasting in a spoiler. The satellite broadcasting receiving antenna has directivity toward a specific broadcasting satellite and can receive clear images or sounds. The gain of the antenna is proportional to the electrical aperture area, and the electrical aperture area is related to the mechanical size. For example, it is known that a parabolic antenna that arranges a reflector and collects radio waves in a pinpoint manner in a pickup can provide a large gain in proportion to the area of the reflector. There is also known an antenna in which a plurality of antenna elements are arranged in parallel and the phases of these antenna elements are electrically combined to improve gain and directivity. With this antenna, the larger the number of antenna elements, the easier it is to obtain gain and sharp or various directivities.
If the antenna elements are arranged so as not to overlap each other to obtain individual characteristics, the mechanical size of the entire antenna also increases.

From this point of view, the antenna for receiving satellite broadcasting tends to be larger than the antenna for GPS,
In the conventional GPS antenna housing structure, the antenna is mounted on the upper surface or inside of the spoiler, so that the influence on the aerodynamic characteristics is small, but it is possible to mount or house the antenna of a size capable of clearly receiving satellite broadcasting. Have a problem that is difficult.
