Description
Com-Power EMI / EMC broadband and tuned antennas cover the frequency range of 9 kHz – 40 GHz. Most electronic products are required meet the various international EMC regulatory standards before they are introduced to the market. Com-Power broadband antennas were designed to test these products for compliance. These antennas can be used for both EMI radiated emission and immunity testing. Some of the EMC standards require testing include FCC Part 15, MIL-STD 461, FAA- DO-160, CISPR22, IEC-1000-4-3, and EN 55022.
Most of these standards allows the use of broadband antennas such as biconical, log periodic, Loop, combilogs and horns. However, they must be calibrated to yield an antenna factors using procedured given in ANSI C63.4 and CISPR 16 in calibrated open area test site (OATS). These factors are applied as a correction to the measurement during EMC product compliance testing.
Dipole antennas are considered the standard antenna to use for site attenuation measurement and as a reference for calibrating biconical and log periodic antennas operating up to 1 GHz. The 41 inch Active Monopole antenna sometime’s referred as rod antenna is used for Mi-lstd 461 and Belcore GR1089 electric field testing below 30 MHz.
Broadband antennas are preferred for automated tests, because it minimizes antenna switching or tuning. They also can handle high input signal to generate electromagnetic fields for radiated immunity testing. They are usually compact enough to fit inside most anechoic chambers. Com-Power biconical, log periodic and horn antennas can be used for both emissions and immunity testing.
