Antenna Coupler CMU-Z11 + CMU-Z10 1150.1008.02 + 1150.0801.10

Broadband Antenna Coupler (CMU-Z10)

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./ RF Shielding Cover (CMU-Z11)

The active coupling zone for frequencies from 770 MHz to 960 MHz, the green circle that for frequencies from 1.7 GHz to 2.2 GHz. Depending
on the radiation center of the phone, the optimum position is different for each model. Since the coupling zone is a defined area, the phone can be shifted somewhat out of the optimum position without dramatically increasing coupling attenuation. These zones are marked on the coupler by means of the antenna elements, which are visible through the  transparent base plate.

Coupling Factor
