Base Station Antenna Mounting Cavity for 4G Signal Reflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current integrated base station antennas suffer from radio frequency signal loss due to backward radiation from the 4G antenna module caused by the opening in the reflecting plate for the 5G antenna module, and mounting difficulties arise when the 5G antenna module is aligned with an inclined 4G antenna module.
Innovation Solution
A mounting assembly comprising a metal frame and rails forms a reflecting cavity to redirect backward radio frequency signals from the 4G antenna module, and includes support elements and fasteners to facilitate easy alignment and fixation of the 5G antenna module on the 4G antenna module, regardless of its orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a reflecting plate with an opening is used to allow 5G signals to radiate forward, then 5G signal transmission is improved, but 4G signals radiate backward from the side gap causing signal loss
Solution Approach 1:
The reflecting plate is segmented into multiple sections: a first reflecting plate section, a second reflecting plate section, and a third reflecting plate section. This segmentation allows different portions of the reflecting plate to serve different functions - some areas reflect 4G signals while others accommodate 5G signal transmission, thereby reducing 4G signal loss while maintaining 5G transmission effectiveness.
Solution Approach 2:
Different regions of the reflecting plate are designed with different properties. The first reflecting plate section has specific structural characteristics optimized for 4G signal reflection, while the second and third sections are configured to accommodate 5G antenna modules and reflect 5G signals. This local differentiation allows each region to optimize its function for the specific signal type.
2Ease of operation
If a hook mechanism is used to mount the 5G antenna module on the 4G antenna module, then vertical mounting is simplified, but mounting becomes difficult when the 4G antenna module is mounted at an angle of inclination
Solution Approach 1:
The support component is designed with multi-functionality to handle both vertical and inclined mounting scenarios. It includes a support body with a support surface that can accommodate the antenna module at various angles, and a fastening mechanism that can secure the module regardless of the 4G antenna module's orientation. This universal design allows the same component to effectively mount antennas in different installation configurations.
Solution Approach 2:
The support component incorporates dynamic adjustment capabilities through its fastening mechanism, which can adapt to different mounting angles. The support structure allows for angular adjustment and positioning, enabling installers to configure the 5G antenna module according to the specific installation requirements whether vertical or inclined mounting is required.
3Reliability
If the 5G antenna module is mounted on the back of the 4G antenna module with a reflecting plate opening, then 5G signals can radiate forward, but side gaps cause 4G signals to radiate backward resulting in signal loss
Solution Approach 1:
The reflecting plate is divided into multiple functional sections including a first reflecting plate section, a second reflecting plate section, and a third reflecting plate section. This segmentation enables different areas to perform different functions - the first section maintains signal reflection while the second and third sections are configured to minimize side gaps and prevent 4G signal leakage, thereby reducing energy loss while preserving 5G radiation capability.
Solution Approach 2:
The design converts the potential harmful effect of side gaps into a beneficial configuration by strategically positioning and shaping the reflecting plate sections. The third reflecting plate section, for example, is specifically configured to close or minimize side gaps that would otherwise cause 4G signal loss, while the overall structure maintains the necessary openings for 5G signal radiation. This transforms the potential problem of signal leakage into an optimized signal management solution.
