This Swissto12 3D Printed  Antenna (above) Array reminds me of the Hooker Headers I installed on 1969 Chevy Camaro SS back in the 1970's.

SWISSto12 3D Printed GEO Antenna Assembly - RF Cafe

3D printing of antenna and waveguide components has been advancing rapidly in the past few years. Early research used plastic that was then coated with a conductive substance. Once 3D printing using a metallic filament was developed to the point that the structure could withstand heat cycling, vibration, and shock associated with aerospace environments, the creation of complex, compound shapes never deemed possible with traditional machining became reality. Using proprietary additive manufacturing techniques developed in-house, virtually any form of waveguide and/or antenna can now be fabricated by companies like Swissto12, based in Renens, Switzerland.

As can be seen in the included images from the Swissto12 website, the surfaces are not perfectly smooth due to the manner in which the 3D printer lays down successive layers of material. At lower frequencies with longer wavelengths surface roughness would not be as much of an issue, but in the 10 GHz and above realm it can be a deal killer. Swissto12 has a process which smoothes the assembly enough to achieve low insertion loss and good VSWR.

No, I do not know the derivation of the company's name.

About RF Cafe

    Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
