As Low Earth Orbit (LEO) constellations continue to expand, the demand for efficient and scalable gateway connections increases. To meet this necessity, more capable antenna systems are required, especially in high-traffic regions where capacity bottlenecks occur. This paper proposes a distributed LEO feeder link, designed to achieve scalable, high throughput connectivity in congested areas. This solution exploits phase-driven array antennas, coordinated in a MultipleInput Multiple-Output (MIMO) configuration to increase the overall ground station throughput. The proposed deployment enables spatial multiplexing without requiring ground synchronization. Additionally, a design and optimization procedure for the MIMO geometry is developed, based on a beam pattern analysis and practical processing schemes. Numerical comparisons with conventional Ka-band feeder solutions, demonstrate the potential of the proposed architecture for enhanced system capacity and scalability.
