At the EMV 2025 tradeshow in Stuttgart, Rohde & Schwarz displays for the first time its R&S HF1444G14 High-gain EMI microwave antenna with outstanding performance. The antenna covers a frequency range from 14.9 GHz to 44 GHz. It meets the requirements of the standards CISPR 16-1-4 and CISPR 16-2-3. Precise mechanical construction and optionally available individual calibration make the antenna ideal for electromagnetic interference measurements. With the R&S HF1444G14 Rohde & Schwarz addresses the trend towards higher frequencies and accelerates and simplifies the test of large objects in smaller chambers.
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. Thanks to its sophisticated and innovative design the antenna shows a market leading electrical performance of high antenna gain (approx. 14 dBi at the center frequency) in combination with a 3 dB half-power beamwidth of more than 28°. 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, thereby requiring a smaller and more cost-efficient EMC chamber.
Furthermore, the antenna meets the requirements of the standard CISPR 16-1-4 and the updated standard CISPR 16-2-3. In the standard update the frequency range 1 GHz to 18 GHz is extended up to 40 GHz and a min. 3 dB half-power beamwidth of 28° is required.
The new EMC antenna is the perfect choice for making full compliance testing up to 44 GHz in combination with the R&S ESW44 EMI test receiver. The system is designed to deliver precise and reliable measurement results quickly. The excellent electrical performance and the resulting benefits position the new EMI antenna as a future-proof investment for EMC test laboratories and manufacturers of complex products or electronic equipment requiring EMI testing like the automotive industry, mobile phone manufacturers, consumer electronics, industry electronics and furthermore. The R&S HF1444G14 High-gain EMI microwave antenna will be available in mid-2025.
