Abstracts: The GTEM (giga hertz transverse electromagnetic cell) is a flared transmission line that is operated in TEM mode to simulate a free space planar wave. It can be used for radiation susceptibility test as well as for the measurements of the radiated emission of electronic equipment at frequency from DC to GHz. As an application radiation pattern of small antenna is evaluated by means of GTEM cell and the results are compared to those obtained an anechoic room. The results indicate possibility for using the GTEM cell for determining certain properties of antenna like the gain or 3 db beam width without usually use costly anechoic rooms
