Antennas

An Antenna is a specialised transducer designed to either capture radiated electromagnetic emissions from a device (for testing compliance) or to radiate a controlled field toward a device (to test its immunity to interference). Unlike standard communications antennas, they are engineered for extreme bandwidth and flat frequency response.

Why Choose an EMC Antenna?

Ultra-Wide Bandwidth: They are designed to cover massive frequency ranges (e.g., 30MHz to 3GHz) in a single sweep, eliminating the need to stop testing and swap antennas mid-measurement.
Calibrated Antenna Factors: Professional EMC antennas come with precise calibration data (Antenna Factors), allowing a spectrum analyser to convert "received voltage" into "field strength" (V/m) accurately.
High Power Handling: For immunity testing, these antennas are built with robust materials to handle high-wattage inputs from RF amplifiers without overheating or distorting the signal.
Minimal Self-Resonance: They are engineered to provide a clean, predictable response across their entire range, ensuring that any peaks or dips seen on the screen are from the device being tested, not the antenna itself.

Core Applications

Radiated Emissions Testing (Pre-compliance): Used to detect if a product is "leaking" excessive electromagnetic noise that could interfere with radios, TVs, or emergency services.
Radiated Immunity Testing: Used in conjunction with an RF amplifier to subject a product to intense electromagnetic fields (e.g., 10 V/m) to ensure it continues to function correctly in harsh environments.
Site Shielding Evaluation: Combined with a comb generator to measure the effectiveness of shielded rooms or "Faraday cages" by seeing how much signal can pass through the walls.
Wireless Coexistence Testing: Verifying how a new electronic device behaves when placed near known high-frequency sources like Wi-Fi routers, 5G towers, or industrial equipment.
