Multi-band Active Antenna with Removable Combiner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of frequency bands in mobile communications leads to a crowded and complex site installation process due to the dispersion of unit parts in existing antenna systems, requiring large spaces for installation and maintenance.
Innovation Solution
A multi-band active antenna design where a combiner is removably connected to a broadband antenna's window, and an active module is connected to a mounting kit, integrating all components into a single unit, reducing site installation space and facilitating installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a broadband antenna, external combiner, and external active module are used separately, then multiple frequency bands can be supported, but site installation space increases and installation becomes difficult
Solution Approach 1:
The patent combines the broadband antenna, combiner, and active module into an integrated multi-band active antenna unit. The combiner is connected to the antenna through a window opening, and the active module is mounted on the antenna structure, merging previously separate components into a single deployable unit that reduces installation space while maintaining multi-frequency band support capability
2Ease of manufacture
If unit parts are dispersed (broadband antenna, combiner, active module as separate components), then each component can be independently optimized, but site installation requires large space
Solution Approach 1:
The patent integrates the combiner and active module with the broadband antenna into a unified structure. The combiner connects through a window on the antenna enclosure, and the active module mounts to the antenna structure, creating a compact integrated unit that maintains component functionality while dramatically reducing the space required for site installation
3Area of stationary object
If components are integrated into one unit, then site installation space is reduced, but maintenance complexity may increase
Solution Approach 1:
While integrating components into a unified antenna structure, the patent maintains functional segmentation through removable connections. The combiner can be removed from the window opening, and the active module can be detached from the mounting bracket, allowing individual component replacement and maintenance without requiring replacement of the entire antenna assembly
