In this paper, a 5G MIMO mobile phone prototype including four antennas working in the 10-13.2 GHz band is designed. The objective of the study is to evaluate the negative impact due to the user's hand in frequencies higher than 10 GHz. A 3D spherical near-field scanner with fixed Antenna Under Test (AUT) is leveraged in order to measure a 3D...

A specific set-up for probe-fed antenna pattern measurements with an articulated arm has been developed with a 500mm AUT-probe distance. This pa per will give an example of far-field measurement and highlight its advantages and limitations. A near-field approach to filter the probe effect is investigated. First measurement results, including...

This paper present a specific set-up developed for antenna pattern measurements of probe-fed antenna with a 500mm AUT-probe distance. An example of Near-Field measurement is proposed and shows important errors on phase acquisition at 90 GHZ. Raw measurements are improved using a spherical correction based on laser-tracker structural data. Phase...
