Antenna Module Positioning Clamp for Signal Interference Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional signal transmission devices experience interference and non-uniform radiation patterns, particularly at high frequencies like 28 GHz, due to the placement of antenna modules on printed circuit boards, which affects transmission quality.
Innovation Solution
A signal transmission device is designed with a heat dissipation member and a positioning clamp that restricts the antenna module, featuring clamp openings and spacing ribs to minimize interference, along with a heat dissipation member that reduces thermal interference and improves heat dissipation, allowing for better antenna placement and uniform radiation patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the antenna module is disposed on the printed circuit board at the edge, then the device structure is simple, but the antenna experiences interference from surrounding elements and has non-uniform radiation pattern
Solution Approach 1:
The antenna module is extracted from the printed circuit board and relocated to the device housing. The housing serves as a dedicated mounting structure that isolates the antenna from interfering elements on the circuit board, while the extraction allows the antenna to be positioned in a location that provides better radiation characteristics without being constrained by board layout limitations
Solution Approach 2:
A positioning clamp with specifically designed clamp openings and spacing ribs is introduced as an intermediary component between the antenna module and the housing. This mediator structure provides precise positioning and spacing that maintains uniform radiation patterns while securing the antenna in the optimal location within the housing
2Ease of manufacture
If the antenna module is placed on the printed circuit board, then the manufacturing process is simple, but the radiation pattern is not uniform and transmission quality suffers
Solution Approach 1:
The positioning clamp acts as a precision intermediary that bridges the simple manufacturing process with the requirement for uniform radiation patterns. The clamp's pre-designed geometry with specific clamp openings and spacing ribs ensures accurate antenna positioning and spacing, achieving consistent radiation characteristics without requiring complex manufacturing procedures
Solution Approach 2:
The positioning clamp is designed and prepared in advance with the exact clamp openings and spacing rib configurations needed to achieve uniform radiation patterns. This preliminary preparation of the positioning structure ensures that when the antenna is installed, it automatically achieves the desired radiation characteristics without requiring complex adjustment or calibration during assembly
3Volume of moving object
If surrounding elements are close to the antenna, then the device structure is compact, but the transmission quality is affected by interference
Solution Approach 1:
The housing structure is designed with differentiated local characteristics: the positioning clamp provides tight, precise positioning for the antenna module to maintain compact overall device size, while the clamp openings and spacing ribs create localized clearance zones around the antenna that isolate it from interfering elements, thus maintaining both compactness and transmission quality
