Abstract

The results of preliminary measurements of the properties of two stripline transverse electromagnetic (TEM) cells are presented. The construction of the field cell is illustrated schematically. Measurements of emissions from a standard source made in a stripline TEM cell show good correlation with measurements of the same source made in a semi-anechoic chamber. The stripline TEM cell has several practical advantages over the coax TEM cell for preliminary measurements of electromagnetic emissions. These include lower cost, more convenient access, smaller size for a given working volume, and greater uniformity of response across the width of the cell. Its major disadvantage is greater susceptibility to ambient signals, but this can be overcome by using a shielded or partially shielded room
