Comparing Gains of 28 GHz Module-Based Phased Antenna Arrays on a 5G Mobile Phone

Empirical Evaluation of a 28 GHz Antenna Array on a 5G Mobile Phone Using a Body Phantom

“…11(b) are lower than in the simulations due to the measurement tower shadowing those angular ranges. Although some differences can be seen from there cuts, the measured patterns match well in general with the simulated ones 1) Free space: The CDF of the maximum realized gains in free space across 301 angles covering the entire sphere was calculated according to [18] as shown in Fig. 12(a).…”

“…The array allows us to collect multipath powers arriving from different directions. In this present paper, parts of the reported insights in [18] are empirically verified. We aim at reproducing scattered fields from a realistic human body using a physical body phantom that has a simple shape.…”

“…In this work we decided to use a rectangular stacked patch as an antenna element intended for a mobile phone, which is detailed in [18]. The patch is designed so that it realizes a wide enough bandwidth for radio systems operating around 28 GHz.…”

“…Despite the increasing relevance of NR FR2, the effects of a human body on the gains and losses to the antennas have got relatively little attention at NR FR2. Despite the significant studies [2]- [18] that have given insights into robust mobile phone antenna array configurations at NR FR2 on a realistic environment involving human body effects, clear design guidelines for mobile antenna systems are still missing.…”

“…Antenna array was chosen with the goal to provide generic but realistic-enough example for demonstrating the use of developed phantom. Our exemplary array consists of two modules of patch antenna arrays installed at different sides of a mobile phone chassis, which we reported in [18] as a co-located array. The array allows us to collect multipath powers arriving from different directions.…”
