Abstract :
In this work, two balanced dipole antennas in both the cellular band and the PCS band have been measured using a GTEM (Gigahertz transverse electromagnetic mode) cell and the results have been compared with those obtained using an anechoic room. It is pointed out that correct rotation plane of the antenna under test (AUT) inside the GTEM cell is essential to produce right antenna patterns The effectiveness and limitation of antenna measurements using a GTEM cell and associated measurement uncertainties are discussed.
