Modular Antenna Layout for Heat Dissipation and Interference Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antenna apparatuses face challenges with reduced heat dissipation performance due to the radome shielding the front portion, concentrating heat dissipation on the rear surface, and interference between feed lines and radiating elements, which limits the effectiveness of both digital and analog amplification elements.
Innovation Solution
The antenna apparatus separates the amplification unit module with analog amplification elements onto an intermediate outside air layer between the main board and the RF module, allowing heat to be dissipated in a front-rear direction, and incorporates a finger guard panel to reduce interference between feed lines and radiating elements.

Engineering Contradiction Analysis
1Object-affected harmful factors
If the radome shields the front portion of the antenna apparatus, then protection from external environment is improved, but heat dissipation performance deteriorates
Solution Approach 1:
The antenna apparatus is divided into multiple modular units: a main body module containing the main board, an RF module with antenna elements, and an amplification unit module with analog amplification elements. This segmentation allows each module to be positioned optimally for its function, with heat-generating components placed in locations favorable for heat dissipation while maintaining environmental protection for sensitive components.
Solution Approach 2:
The amplification unit module is positioned on an intermediate outside air layer between the main body module and RF module, utilizing the vertical/dimensional space rather than only horizontal placement. This allows heat to dissipate in multiple directions (front-rear direction as stated in the patent) and prevents heat concentration on the rear surface alone.
2Device complexity
If digital and analog amplification elements are mounted on the rear surface of the main board, then device integration is improved, but heat dissipation performance deteriorates
Solution Approach 1:
The amplification elements are separated from the main board and mounted on a dedicated amplification unit module. This module is then positioned on the intermediate outside air layer, allowing heat to dissipate away from the main board's rear surface while maintaining functional integration of the antenna system.
Solution Approach 2:
The intermediate outside air layer acts as an intermediary space between the main body module and RF module, providing a location for the amplification unit module that facilitates heat dissipation while maintaining electrical and functional connections within the system.
3Volume of moving object
If feed lines and radiating elements are positioned close together, then antenna compactness is improved, but interference between feed lines and radiating elements increases
Solution Approach 1:
The finger guard panel is specifically positioned in the region where feed lines and radiating elements are in close proximity, providing localized interference reduction exactly where needed. This allows the antenna to maintain compact overall dimensions while addressing interference in the critical local area between feed lines and radiating elements.
