R&S CMU-Z10 broadband antenna coupler

The antenna coupler can be used alone or combined with

the R&S CMU-Z11 RF shielding cover to create a fully enclosed

RF shielded chamber.

A λ/4 radiator vertically mounted on the mobile phone

generates a vertically polarized electromagnetic field. The

coupling element in the R&S CMU-Z10 is arranged such

that a mobile phone with a vertically mounted λ/4 radiator

achieves minimum coupling attenuation. The coupler is

of asymmetric design so that measurements can also be

performed on mobile phones with horizontal polarization.
