Antennas

CISPR 25 covers a frequency range of 150 kHz to 2.5 GHz and determines the necessary space needed for testing. Antenna Systems, Monopole Antennas, Biconical Antennas, and Periodic Antennas can all be used under CIPSR 25 testing. 

Limits for the antenna systems used under CISPR 25 testing are as follows:

1. 0,15 to 30 MHz 1 m vertical monopole (where this is not 50 W, a suitable antenna matching unit shall be used);
2. 30 to 200 MHz a biconical antenna used in vertical and horizontal polarization;
3. 200 to 1000 MHz a log-periodic antenna used in horizontal and vertical polarization.

Monopole antennas are used for short wave, medium wave, long wave, and high-frequency measurements to adhere to CISPR 25 standard requirements. Biconical antennas used for CISPR 25 testing must be within the frequency range of 30 MHz to 200 MHz with vertical and horizontal polarization. Log-Periodic antennas used for CISPR 25 testing must be within the frequency range of 200 MHz to 1000 MHz in horizontal and vertical polarization.
