Performance Analysis of a Coaxial Conical Transverse Electromagnetic Wave Cell

In order to realize sweep-frequency calibration for wide band field probes with frequency 10MHz~40GHz, a new type of standard field intensity generation device-coaxial conical transverse electromagnetic wave cell (referred to as co-conical TEM cell) is researched by Beijing Institute of Radio Metrology and Measurement. According to IEC61000-4-20 standard, the standing wave, TEM wave mode, field intensity range, field uniformity and other indicators of the co-conical TEM cell are measured. The results show that this co-conical TEM cell has good performance.
