Antenna module of global position system and manufacturing method therefor

Abstract

The invention relates to an antenna module of a global positioning system, comprising a substrate, a first insulation layer and a second insulation layer; wherein, the substrate refers to the lower surface of a patch antenna; the first insulation layer is coated on the substrate and forms a wiring circuit to further integrate a variety of electronic elements on the substrate according to the wiring circuit. Moreover, the second insulation layer is coated on the first insulation layer in order to completely shield the electronic elements integrated on the substrate, therefore, the antenna module of the global positioning system can shorten the distances between the electronic elements and the antenna to realize best high-frequency characteristics, and save spaces occupied by printed circuit boards and shielding caps to effectively reduce the volumes of the antenna modules, simplify the manufacturing process and reduce production cost.

Description

technical field [0001] The invention relates to an antenna module and a manufacturing method thereof, in particular to an antenna module for a global positioning system and a manufacturing method thereof. Background technique [0002] In recent years, due to the increasing popularity of the application of the Global Positioning System (GPS), especially in navigation and positioning, it is a brand new concept. This technology combining space satellite and communication technology has been vigorously developed in the private market. , anyone can easily get the correct position, direction and distance, even the speed and time can be grasped with one hand, it can be said that the scope of application is quite wide. Therefore, various mobile communication products (such as mobile phones, PDAs, etc.) or related vehicle electronic devices have integrated this function one after another, making GPS also one of the necessary functions. [0003] However, with the rapid development of...

Problems solved by technology

In this way, based on the volume of the printed circuit board 300a and the shielding cover 400a itself, there is a certain limitation on the size and volume of the entire antenna module, which cannot be broken through, so that it cannot meet the demand for exquisite and miniaturized products.

Furthermore, the manufacturing process of the entire antenna module will affect the efficiency and cost of the production process because there are many welding points (500a and 501a) that must be manually welded.
