AI Technical Summary

Technical Problem

In the prior art, the coating layer structure of the tile glass will affect the performance of the broadcast antenna, and it is difficult to arrange the antenna on the backglass with high heating and defrosting performance requirements.

Method used

A laminated component is designed. By setting a coating area and a non-coated area on the substrate, the first antenna segment of the antenna structure is projected in the non-coated area, and the second antenna segment is projected in the coating area. The coating layer is used as the parasitic unit of the antenna to improve the gain and omnidirectionality of the directional pattern.

Benefits of technology

It effectively eliminates the impact of the coating layer on the antenna performance, and improves the low-frequency gain of the antenna by coupling the coating layer, achieving efficient performance support for the antenna.

Abstract

The invention provides a laminated assembly and a vehicle. The laminated assembly comprises a substrate and an antenna structure arranged on the substrate, the substrate comprises a coating area and a non-coating area, the antenna structure comprises a feeding point and a first antenna, the first antenna comprises a first antenna section and a second antenna section, one end of the first antenna section is connected to the feeding point, and the other end of the first antenna section is connected to one end of the second antenna section. The projection of the first antenna section on the substrate is located in the non-film-coating area of the substrate, and the projection of the second antenna section on the substrate is located in the film-coating area of the substrate. Therefore, in the application, the second antenna section of the first antenna can be coupled with the film coating area of the substrate, and the film coating area can serve as a parasitic unit of the first antenna, so that the gain and directional diagram omnidirectivity of the first antenna are improved.
