MatSing unveils large-format Luneburg lens antennas

MatSing has developed a manufacturing process for large-format Luneburg Lens antennas, opening a new approach to multibeam satellite communications.

The California-based radio frequency technology company says the process lets it build Luneburg Lenses at larger sizes and higher frequencies than was previously practical. It is targeting applications in satellite communications, defence, radar and ultra-wideband wireless links.

Luneburg Lenses are a long-established antenna concept, but scaling them for high-frequency, large-aperture applications has posed manufacturing challenges. MatSing says the main obstacles have been the need for very low-loss dielectric materials, precise control of permittivity and tight dimensional tolerances.

It says its materials and production methods address those issues, enabling scalable manufacture of lenses with apertures exceeding 50 wavelengths. The result, it says, is a platform designed to maintain gain, beam quality and broad frequency coverage while supporting multiple beams.

Technical range

The product line spans apertures from 0.5 metres to 2.4 metres and frequencies from 1 GHz to 30 GHz, covering L through Ka band. Gain exceeds 40 dBi at the top of each configuration's operating range, according to MatSing.

Sample configurations include a 1.2-metre lens covering 1 GHz to 18 GHz, a 2.4-metre lens covering 1 GHz to 12 GHz, and a 0.5-metre lens covering 12 GHz to 30 GHz. These formats are intended for multi-band communications, longer-range lower-frequency links and higher-frequency satellite communications, respectively.

MatSing says the lenses are well suited to satellite communications because they provide wide-angle coverage and support simultaneous transmit and receive functions across a range of directions and frequencies. A single lens antenna can link to and track multiple satellites across a broad field of view and multiple frequencies, it says.

This would put the technology in competition with conventional reflector dishes and phased-array systems in parts of the satellite ground equipment market. MatSing argues that lens-based systems can reduce infrastructure requirements where operators need broad coverage and multiple beams from a single antenna system.

Market uses

Beyond satellite gateways, the company lists potential uses in low Earth orbit, medium Earth orbit and geostationary communications, teleports, passive radio frequency sensing, multifunction radar, radio astronomy, deep-space communications and mobile satellite links for maritime, airborne and land applications.

MatSing is best known for lens-based antenna systems used in wireless networks and large venues, and the new development extends that expertise into satellite and sensing markets. The company was founded in Singapore and is now headquartered in Irvine, California.

Leo Matytsine, Executive Vice President at MatSing, described the manufacturing challenge in terms of the effect of small variations across larger apertures. "Even small material variations can introduce phase errors as aperture size increases, significantly reducing gain and beam quality. This MatSing manufacturing breakthrough overcomes these challenges, transforming the large-format Luneburg Lens from a laboratory concept into a practical engineering platform delivering superior performance and efficiency," he said.

MatSing says the new lenses will be used in its next-generation LensSAT satellite antennas, with options for custom frequency ranges, aperture sizes and integration. This suggests the company is positioning the technology both as a product platform and as a basis for tailored systems in specialist communications and sensing applications.

The company also emphasised the breadth of frequency coverage available from a single architecture. In a market where satellite operators and government users often need equipment that can work across different bands and orbit classes, that flexibility could be relevant to ground-system design.

Matytsine said the implications go beyond a single antenna format. "As satellite communications, defense sensing and advanced wireless infrastructure continue to evolve, RF lens technology has the potential to become a catalyst for the next generation of global connectivity," he said.
