Types of antennas used for commercial radiated measurements
There are three types of antennas used for commercial radiated emissions
measurements:
• Biconical antenna: 30 MHz to 300 MHz
• Log periodic antenna: 200 MHz to 1 GHz (the biconical and log periodic overlap
frequency)
• Broadband antenna: 30 MHz to 1 GHz (larger format than the biconical or log
periodic antennas)
