The world of ElectroMagnetic Compatibility (EMC) is evolving fast. New technologies such as 5G, the Internet of Things (IoT), and electric vehicles (EVs) are reshaping how engineers design, measure, and verify electronic systems. Each of these innovations introduces unique EMC challenges that demand higher precision and more flexible test setups, especially in high-frequency EMC testing.
Emerging Technologies, Emerging Challenges
For example, with the introduction of 5G, test systems must operate over a much wider frequency spectrum, including millimetre-wave bands. These high frequencies cause increased signal loss and different reflection patterns, while complex transmission methods like beamforming and MIMO require advanced measurement strategies. Equipment must remain stable and accurate even in fast-changing, high-frequency environments.
IoT adds another layer of complexity. Millions of connected devices now operate simultaneously in homes, factories, and vehicles. Their low-power, continuous emissions may overlap and create unpredictable interference. As a result, EMC testing must address denser, more dynamic signal environments and use faster test cycles.
Electric vehicles combine high-voltage power electronics with sensitive communication and control systems. This mix of strong emissions and delicate receivers makes EMC assurance critical to both safety and performance. Testing therefore requires higher power levels, broader bandwidths, and specialised automotive standards such as ISO 11451-2 and CISPR 25.
These technologies push EMC testing into higher frequency ranges; often well into millimeter-wave bands above 24 GHz. At these frequencies, EMC test chambers, antennas, and probes must maintain exceptional accuracy, as even small losses or reflections can affect measurement results. This becomes increasingly challenging because measurement uncertainty rises with frequency, making low-anisotropy field probes like the RadiSense® crucial for ensuring consistent and traceable high-frequency EMC testing performance.
