Active Monopole Antenna
This Biconical antenna is the standard workhorse of any EMC test house for emissions testing.
Electromagnetic Compatibility (EMC) testing in the railway industry requires a range of specialized antennas to measure both radiated emissions and immunity across various frequency ranges, ensuring compliance with standards such as EN 50121 and IEC 61000. Biconical antennas, typically covering 20 MHz to 300 MHz, are used for radiated emissions and immunity tests in the lower frequency range due to their wideband performance and omnidirectional characteristics. Log-Periodic Dipole Array (LPDA) antennas, operating from approximately 200 MHz to 1 GHz, provide high gain and directional properties, making them ideal for emission and immunity tests in the VHF and UHF bands. For higher frequencies, horn antennas, which generally cover 1 GHz to 18 GHz or beyond, offer high directivity and efficient power handling, making them essential for immunity testing and emission measurements.
At lower frequencies, loop antennas, covering 9 kHz to 30 MHz, are used to assess magnetic field emissions and immunity, particularly in railway signaling and power systems, while rod (monopole) antennas serve a similar role in measuring electric field emissions in the same frequency range. Additionally, hybrid antennas, such as Biconilog antennas, combine biconical and log-periodic designs to provide a broad frequency range from 30 MHz to 3 GHz, offering a single-antenna solution for multiple EMC tests. These antennas are critical for ensuring railway systems meet electromagnetic compatibility requirements, preventing interference with onboard electronics, signaling equipment, and infrastructure.
