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 ?/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 ?/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.
