Com-Power AL-130 Application
The loop antenna is utilized for testing to meet the various EMC requirements specified by FCC, CISPR, MIL-STD and EN. This antenna is specified for open field emissions testing below 30 MHz It is assumed that in the far field the ratio of E and H field will remain the same as the characteristic impedance of the medium.
The loop antenna is positioned with its plane vertical at the specified distance from the EUT. In addition to the EUT rotation, the loop antenna also has to be rotated about its vertical and horizontal axis to maximize emissions. This procedure is described in detail in ANSI C63.4.
Monopole antennas (such as the AM-741) also operate in the same frequency range as a loop antenna, but are used for E-field measurements and require a counter poise.
