TEM-cell with 75 /spl Omega/ impedance for EMC measurements

This work gives an insight into the TEM-cells, their use and application. It deals with problems regarding the characteristic impedance, higher mode, dimensions and usable test area. A TEM-cell designed at FER is presented with initial results. This TEM-cell has a characteristic impedance of 75 /spl Omega/ and an increased usable test area. It can be utilized for GSM as well as EMC measurements at 900 MHz due to the uniform TEM field on this frequency.
