Insert-Molded Antenna Pattern Embedded in Electronic Device Casing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional antenna manufacturing for electronic devices is cumbersome and costly, as antennas are typically individually manufactured and separately mounted within devices, leading to increased complexity and expenses.
Innovation Solution
An antenna device with an insert-molded antenna pattern is directly embedded inside the casing of electronic devices using the insert-molding process, allowing for either direct wire connection or coupling with an antenna signal feeding line, enabling efficient integration and reduced manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If antennas are individually manufactured and separately mounted in electronic devices, then antenna performance can be optimized, but manufacturing complexity and cost increase
Solution Approach 1:
The patent combines the antenna structure with the device casing by embedding the antenna pattern directly into the casing material. This merging eliminates the need for separate antenna manufacturing and mounting processes, reducing manufacturing complexity while maintaining antenna functionality through the integrated design.
Solution Approach 2:
The device casing serves dual functions: it provides structural protection and simultaneously acts as the antenna structure. The casing material is designed to perform both mechanical support and electromagnetic radiation/reception functions, eliminating the need for dedicated separate antenna components.
2Manufacturing precision
If antennas are individually manufactured and separately mounted, then antenna characteristics can be precisely controlled, but manufacturing cost increases
Solution Approach 1:
The antenna pattern is embedded within the casing material during the casing manufacturing process itself. This combined approach allows precise control of antenna characteristics through material composition and structure design while eliminating separate antenna manufacturing and assembly steps, thereby reducing overall manufacturing cost.
Solution Approach 2:
The antenna pattern is prepared and embedded within the casing material before the final device assembly. This preliminary integration ensures precise antenna characteristics are established during casing formation, avoiding costly post-assembly adjustments or separate mounting operations.
3Ease of operation
If separate antenna mounting is used, then antenna replacement and adjustment are possible, but device assembly becomes more troublesome
Solution Approach 1:
The antenna structure is merged with the casing as a single integrated component. This eliminates separate antenna mounting steps and reduces assembly complexity, as the antenna is already positioned and secured within the casing structure during its formation.
Solution Approach 2:
The casing serves as both the housing and the antenna mounting structure. This multi-functional design simplifies the assembly process by eliminating the need for separate antenna brackets, adhesives, or fastening mechanisms that would be required in traditional separate mounting approaches.

AI summary
Disclosed is an antenna device for transceiving a wireless signal with an insert-molded antenna pattern embedded inside a casing of an electronic device. The insert-molded antenna pattern is connected to an antenna module of a motherboard of the electronic device in order to feed the wireless signal transceived by the insert-molded antenna pattern through an antenna signal feeding line connected to the insert-molded antenna pattern and the antenna module, or by an antenna coupling element coupled with the insert-molded antenna pattern.
