Patent ID: 7994991

Claim:
A system for measuring the radiation diagram of a transmitting antenna, the system including: (a) a receiver device provided with at least one fixed receiving antenna for picking up an electromagnetic field to be measured and generated by a transmitting antenna to be belonging to an electronic device; (b) a positioning device, on which a support element for the electronic device is placed, wherein the positioning device includes: i, means for driving the support element in rotation with the electronic device; ii, detection means for detecting position or orientation of the transmitting antenna; and iii, a data processing station for processing data supplied by the detection means and by the receiver device, wherein the support element is a spherical hollow element that houses the electronic device and the transmitting antenna, and the spherical element is held on the positioning device by gravity on three points of first support, wherein one point of first support is formed by a drive member in contact with an external surface of the spherical element so as to rotate the spherical element randomly in every direction on the positioning device, and the other two points of first support of the positioning device are each formed by a ball and socket joint, wherein the ball is placed to rotate freely in an end housing of the ball and socket joint so that one portion of the ball emerges through an aperture in the housing to come into contact with the external surface of the spherical element.
