Key facts R&S CMU-Z10 broadband Antennas' class='regSlim'>antenna coupler The Antennas' class='regSlim'>antenna coupler can be used alone or combined with the R&S CMU-Z11 RF shielding cover to create a fully enclosed RF shielded Chambers' class='regSlim'>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.
