Abstract

The present invention provides an antenna unit in which a packaged outer shell is directly mounted on a substrate on which an inner shell is mounted, thereby reducing unevenness in the gap between the outer shell and a mounted surface. The antenna unit comprises: a base body (10) having a base body side fitting part; antenna elements (20, 30) arranged on the base body (10); covering the antenna elements (20, 30) and fixed inside the base body (10); A shell (40); an outer shell (50) covering the inner shell (40) and mounted on the base (10). The housing (50) has a housing-side fitting portion that fits into the base-side fitting portion.

Description

technical field [0001] The present invention relates to an antenna unit suitable for applications such as installation on a roof of an automobile body. Background technique [0002] The vehicle-mounted antenna unit installed on the roof of a vehicle body is roughly divided into a vehicle-mounted antenna unit having a single-layer casing structure and a vehicle-mounted antenna unit having a double-layer casing structure. [0003] The single-layer case structure is a structure in which a single case realizes both the waterproof function of the antenna element and the function as a painted case. In this case, it is necessary to paint the casing according to the paint color of the vehicle, but it is necessary to store the antenna units in the quantity corresponding to the set colors of the vehicle as inventory in the factory, which imposes a burden on the inventory space of the production line. pressure. [0004] The double-layer case structure has an inner case and an outer c...
