Slot Arrays
Optisys slot arrays are purpose-built for modern space and aerospace platforms where performance, repeatability, and manufacturability matter just as much as raw RF numbers. By designing slot arrays specifically for additive manufacturing, we take advantage of geometric freedom that traditional fabrication simply can’t match. This allows us to tightly control form factor, integrate multiple RF and mechanical features into a single monolithic part, and deliver highly repeatable performance across builds. The result is a robust, flight-ready antenna that reduces part count, assembly risk, and overall program complexity—while meeting demanding size, weight, and power constraints.
This enables Optisys to efficiently scale designs, tailor aperture shapes to non-traditional envelopes, and embed features such as such as waveguide, combiners, diplexers, and mounting interfaces directly into the structure. Combined with our production-proven processes, this approach delivers consistent RF performance, faster lead times, and lower lifecycle cost compared to conventional multi-piece antenna assemblies.
Typical slot array performance characteristics include:
-
Medium to high gain, depending on aperture size and array configuration
-
Narrow to moderate bandwidth, ideal for mission-specific frequency allocations
-
Excellent SWaP efficiency driven by compact apertures and integrated structures
-
High repeatability and unit-to-unit consistency
-
Reduced mass and part count through monolithic, additively manufactured designs
-
Scalable architectures are well-suited for constellation and at-quantity production
Why Additive Manufacturing Matters Here
Slot arrays benefit uniquely from additive manufacturing because their RF performance is fundamentally tied to precise, repeatable geometry. Additive manufacturing allows Optisys to realize complex internal features, non-traditional apertures, and tightly integrated RF paths that are impractical or impossible to produce with conventional manufacturing. This enables true design-for-performance rather than design-for-manufacturing compromise.
By printing slot arrays as monolithic structures, Optisys eliminates mechanical interfaces, reduces assembly and alignment risk, and embeds multiple functions directly into the antenna. The result is a lighter, more compact, and more robust solution with consistent RF performance across builds. Just as importantly, additive manufacturing supports rapid iteration, form-factor customization, and efficient scaling to at-quantity production without sacrificing repeatability or quality.
Optisys designs are covered by one or more patents.
