Abstract
A measurement device for measuring performance of at least one antenna system in a first frequency band and in a second frequency band. The measurement device including an outer chamber having inwardly radio frequency reflective walls configured to enclose the antenna system, an inner chamber deployable inside the outer chamber, the inner chamber having radio frequency absorptive walls configured to enclose the antenna system, a first test antenna arrangement arranged inside the outer chamber and configured for a measurement operation in the first frequency band, and a second test antenna arrangement arranged inside the inner chamber and configured for a measurement operation in the second frequency band, thereby enabling measuring performance of the antenna system in a reflective radio frequency environment by the first test antenna arrangement and measuring performance in an essentially anechoic radio frequency environment by the second test antenna arrangement.
