3D Multiplexer Layout for Compact Array Antenna Wiring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing array antenna modules in low-orbit satellites have a close arrangement distance between transmitting and receiving antennas, making signal transmission and wiring difficult, which complicates the design.
Innovation Solution
A multiplexer is introduced in the array antenna module, with a first end connected to the array antenna and at least two second ends connected to the beamforming module, allowing for signal transmission between the two components. The multiplexer is designed with different layers for the first and second ends, facilitating signal conduction and reducing spatial requirements.

Engineering Contradiction Analysis
1Area of stationary object
If the arrangement distance between transmitting antennas and receiving antennas is reduced to decrease the overall area, then the area of the antenna design is reduced, but signal transmission and wiring between antennas becomes difficult
Solution Approach 1:
The patent transitions from a planar two-dimensional layout to a three-dimensional stacked architecture. The multiplexer and array antenna are arranged in different layers vertically, allowing signal transmission paths to extend in the vertical dimension rather than being constrained to horizontal plane. This dimensional change enables compact area utilization while maintaining adequate signal transmission paths and wiring space.
2Productivity
If a multiplexer is introduced to improve signal conduction, then signal transmission efficiency is improved, but device complexity increases
Solution Approach 1:
The multiplexer is designed to perform multiple functions: it serves as both a signal distribution hub connecting multiple antennas to the beamforming module and as a spatial organizer that manages wiring between different layers. By integrating these functions into a single component, the overall device complexity is managed while achieving improved signal conduction efficiency.
