Embodiment Construction
[0023] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.
[0024] see figure 1 , which is a schematic structural diagram of the first embodiment of the vehicle-mounted antenna of the present invention. The vehicle-mounted antenna includes a housing 1 made of plastic and an antenna radiating portion 2 disposed on the inner surface of the housing 1 .
[0025] The housing 1 is shaped like a shark's fin and has a cavity (not labeled). The antenna radiating part 2 is spirally wound on the inner wall of the housing 1 . Specifically, it is formed on the inner wall surface of the cavity of the housing 1 through a laser direct structuring process (Laser Direct structuring, LDS for short). The following steps can be taken to form the antenna radiating part 2: (1) Injection molding the housing 1 with a ca...
