The R&S HF1444G14 High-gain EMI microwave antenna with exceptional performance is being unveiled for the first time at the EMV 2025 tradeshow in Stuttgart. It covers a frequency range of 14.9 GHz to 44 GHz and satisfies the requirements of the standards CISPR 16-1-4 and CISPR 16-2-3.
Its precise mechanical construction and optional individual calibration make it perfect for measuring electromagnetic interference. Rohde & Schwarz’s R&S HF1444G14 addresses the trend towards higher frequencies and speeds up and streamlines the testing of large objects in smaller chambers.
With a single measurement, the antenna can fully illuminate an Equipment Under Test (EUT) with a cylindrical volume of 1.5 m x 1.5 m from a distance of 3 m. This efficiency not only reduces measurement time, enabling higher throughput, but also allows the antenna to be placed closer to the EUT, requiring a smaller and more efficient antenna.
The new High-gain EMI microwave antenna extends the frequency range of Rohde & Schwarz’ EMC measurement antenna portfolio up to 44 GHz, enabling EMI measurements of devices in the FR2 range.
Additionally, the antenna satisfies both the upgraded standard CISPR 16-2-3 and the standard CISPR 16-1-4 standards. The standard update requires a minimum 3 dB half-power beamwidth of 28° and extends the frequency range of 1 GHz to 18 GHz up to 40 GHz.
When used with the R&S ESW44 EMI test receiver, the new EMC antenna is the ideal option for doing complete compliance testing up to 44 GHz. The technology is meant to provide fast, accurate, and trustworthy measuring results.
The new EMI antenna is positioned as a future-proof investment for EMC test laboratories and manufacturers of complex products or electronic equipment that require EMI testing, such as the automotive industry, mobile phone manufacturers, consumer electronics, industry electronics, and more, due to its excellent electrical performance and the benefits that follow.
