The National Institute of Standards and Technology (NIST) has launched a new calibration service, SKU63102S, for dual-ridge horn antennas. This service reduces gain uncertainty to plus or minus 0.07 decibels across the 1 to 18 gigahertz frequency range.
Why it matters
High gain uncertainty in dual-ridge horn antennas, often ranging from 1 to 2 decibels, stems from significant multipath reflections. This new service improves measurement precision by mitigating those reflections, streamlining requirements for broadband antenna characterization.
The new service achieves a gain uncertainty of plus or minus 0.07 decibels, a significant improvement over the typical 1 to 2 decibel uncertainty found in uncalibrated dual-ridge horn antennas. This calibration covers the full 1 to 18 gigahertz spectrum using a single service identifier, SKU63102S.
The players
NIST Communications Technology Laboratory
A research division of the National Institute of Standards and Technology focused on advanced radio frequency and communications metrology.
Robotically Enhanced Antenna Laboratory for Metrology
A specialized NIST facility dedicated to precision antenna measurements using automated multi-robot positioning systems.
The details
To achieve this precision, researchers at the Robotically Enhanced Antenna Laboratory for Metrology employ the Large Antenna Positioning System, a dual-robot platform that moves antenna pairs into kinematically calibrated poses. The system uses multirobot motion to stir electromagnetic echoes against anechoic foam walls, allowing for effective signal averaging. This process removes the need for the 20 reference antennas traditionally required to span the 1 to 18 gigahertz range.

The Tech Race
This calibration service reflects a broader industry shift toward high-precision metrology for broadband antenna systems. It follows the institution's ongoing effort to reduce measurement uncertainty in hardware essential for 5G, 6G, and aerospace telecommunications.
Engineers and labs requiring precise antenna gain measurements can now access this standardized calibration via the NIST shop portal. This service replaces the labor-intensive process of using 20 reference antennas to cover the 1 to 18 gigahertz range.
The takeaway
By reducing gain uncertainty to 0.07 decibels, NIST provides a new benchmark for antenna testing that drastically simplifies high-frequency broadband characterization. Industry players should monitor the adoption of SKU63102S to see if it becomes the new standard for commercial radio frequency hardware.
