Abstract
Transverse electromagnetic (TEM) cell is usually used to evaluate the electromagnetic immunity and electromagnetic radiation disturbance of the equipment under test (EUT) and integrated circuit (IC). Affected by the structure of the TEM cell, high-order modes and reflection will be generated in the high frequency range, which will limit the higher frequency applications of the TEM cell. In this paper, the TEM cell specified in IEC61967-2 standard is improved by adopting several methods, including segmented impedance matching, slitting outer conductor, slotting inner conductor, adding absorbing materials and adding an external shielding box. The results show that the improved TEM cell voltage standing wave ratio (VSWR) is less than 1.2 in 0-3.4 GHz, less than 1.3 in 0-3.75 GHz, and less than 1.5 in 0-4.06 GHz; at the same time, the S-parameter characteristics are better.
