Title:
アンテナシステム用の改良された測定装置
Document Type and Number:
Japanese Patent JP7162728
Kind Code:
B2
Abstract:
A measurement device for measuring performance of at least one antenna system (110) in a first frequency band and in a second frequency band. The measurement device comprising an outer chamber (120) having inwardly radio frequency reflective walls (121) configured to enclose the antenna system (110), an inner chamber (140) deployable inside the outer chamber (120), the inner chamber (140) having radio frequency absorptive walls (141) configured to enclose the antenna system (110), a first test antenna arrangement (130) arranged inside the outer chamber (120) and configured for a measurement operation (131) in the first frequency band, and a second test antenna arrangement (150) arranged inside the inner chamber (140) and configured for a measurement operation (151) in the second frequency band, thereby enabling measuring performance of the antenna system (110) in a reflective radio frequency environment by the first test antenna arrangement (130) and measuring performance in an essentially anechoic radio frequency environment by the second test antenna arrangement (150).
