“…The StarLab system is based on patented probe array technology and A-MST [1,2]. Field sampling is performed by a wide band probe array composed of a number of evenly spaced elements along the circumference of the support structure.…”

“…The RF signals from the probes are combined using a passive powercombining network located inside the probe array [1,2]. The use of a passive network provides reciprocity: if the probe array is used in transmit mode the same network acts as a power-splitter feeding all of the probes.…”

“…The new system offers wider bandwidth, the speed advantages of a probe array while the mechanical rotation allows for unlimited angular resolution over the full sphere. The StarLab test station is aimed at the characterization of wireless terminals for development, pre-qualification or pass/fail production purposes [1]. It is a flexible measurement system with functionalities that can be easily extended depending on the needs of the user.…”

“…Those measurements require a rather long measurement time, since the AUT needs to be moved around the two rotation axes of a two-axis antenna positioner, or at least around one axis e.g. if the field probe can be moved on a circular path around the AUT. There have been efforts to avoid mechanical movements by using a circular multi-probe system and rotating the AUT only around the vertical axis [2]. Such systems enable very fast measurements, and have been found to be suitable especially for wireless communication applications [2].…”

We give an overview of research performed during previous years on the development ofmethodsfor measuring and determining the radiation patterns ofsmall antennas. The work has focused on developing a spherical multi-probe system for measuring the 3-D complex radiation patterns ofsmall antennas, as e.g. used in mobile terminals, without the need to move the device under test during the measurement. A demonstrator system with 32 dual-polarisedfield probes has been manufactured and evaluated. The frequency range of the measurement system covers most of the current mobile communications systems, i.e. from 800 MHz to 3 GHz. The radius of the measurement sphere is 1 m. The far field is determined with the spherical-wave expansionbased near-field to far-field transformation from the signals measured at each probe port. Since the system allows measuring a 3-D pattern within seconds, it facilitates specific research that would not be feasible with traditional measurement techniques. Some of these new results are presented. Finally, foreseen future developments ofthese measurement methods are presented.
