TBMA3
Log Periodic Measurement Antenna
CISPR 16 divides the frequency range into several bands and defines specific antennas for each of these bands. For the frequency range above 300 MHz up to 1 GHz, CISPR 16 specifies using logarithmic periodic antennas (log-periodic antennas ) for radiated noise measurements. The TBMA3 is an affordable logarithmic periodic measurement antenna, targeting radiated noise EMC precompliance testing. The TBMA3 is characterized from 250 MHz to 1.3 GHz and has VSWR and antenna factor values typical for log-periodic measurement antennas.
