Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Satellite gateway antennas operating in the Ka and V uplink bands cause interference with 5G base stations due to shared frequency bands, necessitating radiation intensity reduction below FCC-mandated limits without modifying the antenna structure.
Innovation Solution
Deploy physically separate panels with specific size, shape, position, and orientation relative to the satellite gateway antenna to redirect and absorb radiation, mitigating interference in targeted directions without altering the existing antenna design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the satellite gateway antenna transmits in the Ka and V uplink bands, then the satellite broadband internet service is provided, but interference is caused to 5G base stations operating in mm-wave bands
Solution Approach 1:
A passive panel structure is introduced as an intermediary element between the satellite gateway antenna and the 5G base station. The panel redirects radiation in specific directions without requiring active components or power consumption, effectively mediating the electromagnetic interaction while maintaining both satellite and 5G operations
Solution Approach 2:
The panel is designed with specific local properties (size, shape, orientation, position) tailored to the particular interference scenario. By optimizing these local characteristics, the solution reduces radiation intensity in specific directions toward the 5G base station while preserving satellite communication performance in other directions
2Object-affected harmful factors
If the main reflector surface or feed horn is modified to reduce back lobe radiation, then interference mitigation is achieved, but antenna performance and structural robustness are compromised
Solution Approach 1:
The interference mitigation function is extracted from the antenna structure itself and implemented by a separate, independent panel. This allows the antenna to maintain its original design and performance characteristics while the panel handles the radiation redirection function, avoiding any compromise to antenna reliability
Solution Approach 2:
The system is segmented into two independent components: the satellite gateway antenna and the passive panel. This segmentation allows each component to be optimized independently - the antenna for satellite performance and the panel for interference mitigation - without compromising either function
3Object-affected harmful factors
If physically separate panels are deployed to reduce radiation in specific directions, then interference with 5G base stations is mitigated, but device complexity increases
Solution Approach 1:
The panel is designed as a simple, passive structure without complex active components. By using basic reflective geometry rather than sophisticated active interference cancellation systems, the solution achieves interference mitigation with minimal complexity and cost

AI summary
Systems and methods for mitigating interference from a satellite gateway antenna are disclosed herein. In an embodiment, a method for mitigating interference from a satellite gateway antenna includes determining a power flux density radiation from the satellite gateway antenna in at least one direction in a horizontal plane, mounting at least one panel at an area in the at least one direction in the horizontal plane, orienting the at least one panel to have an azimuthal rotation relative to a look direction of the satellite gateway antenna in the horizontal plane, and orienting the at least one panel to have an upward tilt such that any reflection of horizontal rays of the power flux density radiation off of the at least one panel is not in the horizontal plane.
