RF SPIN secured US Patent No. 12,665,315 on June 23, 2026, for a 3D-printed lens technology designed to enhance horn antenna performance. The innovation allows measurement systems to achieve higher signal levels by focusing electromagnetic waves into narrower beams.
Why it matters
This technology enables engineers to increase antenna signal gain without needing to enlarge the horn aperture itself. It provides a specialized solution for systems requiring high directivity within existing physical constraints.
The lens technology increases antenna length by 10-40% and adds between 25 g and 610 g in weight to the units. These lens-equipped models support maximum continuous-wave input powers of up to 150 W across a frequency range of 500 MHz to 44 GHz.
The players
RF SPIN
RF SPIN is a specialized manufacturer of antennas and electromagnetic measurement solutions.
The details
The lenses are manufactured using ASA engineering polymer and are positioned at the aperture of single- and dual-polarized horn antennas to modify wave propagation. Specifically, the DRH18-EC model shows an average gain improvement of 6.5 dB across its 1 to 18 GHz operating band.
Timeline
June 23, 2026: US Patent No. 12,665,315 was officially granted.
October 12, 2026: The technological advancements of this antenna lens system were documented.
The Tech Race
This development follows a pattern set by the broader adoption of additive manufacturing to optimize electromagnetic propagation in antenna design. It highlights how companies are using specialized polymers to replace heavier legacy components and improve technical efficiency in a competitive hardware sector.
For engineers and system designers, this technology offers a way to improve signal gain without increasing the physical footprint of their antenna arrays. Users must account for the added weight and length of the lens when integrating these components into existing measurement systems.
The takeaway
The use of 3D-printed polymer lenses demonstrates a move toward lightweight, high-performance modifications for standard hardware. Integrating these components requires careful attention to the increased physical mass and potential space requirements for the updated antenna models.
