Antenna Connection Structure for Module Clearance and Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bracket structures fail to effectively isolate two different antenna modules, such as Wi-Fi and DECT antennas, from each other and metal parts like heat dissipation structures, leading to reduced antenna efficiency and affected radiation characteristics.
Innovation Solution
A connection structure with a fitting part, a fixing part, and a turning part is designed to detachably connect the second antenna module to the communication base, maintaining a sufficient distance from both the first antenna module and the heat dissipation structure, thereby reducing interference and metal part influence.

Engineering Contradiction Analysis
1Volume of moving object
If the DECT antenna is placed on the same base as the Wi-Fi antenna, then the antenna structure is compact, but the antenna clearance area is insufficient causing mutual interference
Solution Approach 1:
The patent divides the antenna support structure into separate modules: the Wi-Fi antenna is mounted on the base while the DECT antenna is mounted on an independent heat dissipation structure. This segmentation allows each antenna to have its own dedicated mounting space, ensuring sufficient clearance area and avoiding mutual interference while keeping the overall structure compact.
Solution Approach 2:
The heat dissipation structure serves as an intermediary component between the base and the DECT antenna. By placing the DECT antenna on this intermediate structure rather than directly on the base, the patent creates sufficient spatial separation from the Wi-Fi antenna, eliminating mutual interference while maintaining a compact overall design.
2Object-affected harmful factors
If a large base is used to keep antennas far apart, then the antenna clearance area is sufficient, but the cost increases
Solution Approach 1:
Instead of using a large base to accommodate both antennas with sufficient clearance, the patent segments the antenna mounting functions: the Wi-Fi antenna uses the base while the DECT antenna uses the heat dissipation structure. This segmentation achieves the required antenna clearance area without increasing base size, thereby controlling manufacturing costs.
Solution Approach 2:
The heat dissipation structure serves multiple functions: it provides thermal management for the device and simultaneously serves as the mounting structure for the DECT antenna. This multi-functionality eliminates the need for additional support structures, reducing overall manufacturing cost while maintaining sufficient antenna clearance.

AI summary
A connection structure has an extension direction and includes a fitting part, a fixing part, and a turning part. The fitting part includes two joint surfaces. The fixing part includes a surface. The turning part is connected between the fitting part and the fixing part, and the turning part is inclined relative to the fitting part and the fixing part. One of the two joint surfaces of the fitting part faces a same direction as the surface of the fixing part. An offset distance is between one of the two joint surfaces and the surface along a direction vertical to the extension direction. Thus, the connection structure of the present disclosure can prevent two different antenna modules in the electronic device from interfering with each other.
