The reverberation chambers, which are electromagnetic test structures are alternative to the

anechoic chambers because of the installation cost is much lower than the anechoic chamber. In order

for a room to be reverberation chamber, the level of the electric field must be determined and electric

field uniformity must be provided in the room. In order to have a uniform electric field in the room, the

standard deviation of the maximum electric fields must be 4dB between 80 MHz and 100MHz, linearly

decrease from 4dB to 3dB from 100MHz to 400MHz, and below 3dB above 400MHz. Obtaining the

electric field uniformity depends on the parameters such as the placement of the stirrer in the room and

the stirrer position and size, transmitter antenna position, room dimensions. In this study, the effect of

the placement of the stirrer in the room was examined for the uniformity of the electric field, and as a

result of the simulation performed, it was seen that the stirrer contributed significantly to the uniformity

of the electric field.
