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

Implementation of an antenna array on a 5G mobile phone chassis is crucial in ensuring the radio link quality, especially at the millimeter-waves. However, we generally lack the ability to design antennas under practical operational conditions involving body effects of a mobile user in a repeatable manner. We developed numerical and physical phantoms of a human body for evaluation of mobile handse...
