Abstract :
Antenna factor is the main parameter in EMC measurement. Therefore, accurate and low uncertainty antenna is important in order to gain a reliable antenna factor. Direct feed biconical antenna has low uncertainty because balun can be eliminated in the design. Furthermore, the biconical antenna has fix phase center. This paper focuses on type of connectors and antenna sizes that are suitable to be used as a calibration antenna. The return loss for frequency range between 200Mz to 2GHz was measured using network analyzer and found to vary between 10dB to 20dB.
