1024 Antenna Array
(Integrated by 4 256-array)
About
The Y.BEAM module is designed for Ka-band active array antennas
used in LEO ground stations. Its architecture consists of four distinct
panels, with each panel accommodating a 256-element sub-array.
The utilization of LTCC technology in crafting these antenna elements
guarantees exceptional performance in communication, even when
facing the formidable challenges presented by the dynamic and rapidly
changing LEO environment. This innovative module represents a
significant advancement in ground station technology, enabling robust
and reliable connectivity with LEO satellites.
Beam forming, Beam Tracking and Low-Temperature Co-Fired Ceramic
The triumvirate of mmWave beam forming, beam tracking, and LTCC technology collaboratively ensures that LEO satellite communications are not only feasible but also highly efficient and reliable. This combination empowers ground stations to maintain constant contact with LEO satellites, unlocking a wealth of possibilities in satellite-based services and applications.
Beam forming harnesses the power of mmWave frequencies to dynamically shape and steer antenna beams, enhancing signal strength and reducing interference. In LEO, where satellites move swiftly across the sky, the adaptability of beam forming is crucial. It ensures that the narrow, high-frequency beams are accurately directed toward LEO satellites as they traverse the horizon.
Beam tracking complements beam forming by continuously adjusting the antenna’s direction to follow the satellite’s movement. This dynamic tracking capability optimizes signal reception and transmission, maintaining a robust and uninterrupted link with LEO satellites. The rapid response of mmWave beam forming and tracking is indispensable in the challenging LEO environment.
Underpinning these functionalities is LTCC technology, which provides the physical foundation for mmWave antenna arrays. LTCC’s electrical properties and thermal stability make it an ideal substrate for constructing high-frequency, compact antenna modules. Its integration capabilities enable the creation of multi-element antenna arrays in a small form factor, a vital aspect for LEO ground stations where space is at a premium.
