Abstract

In fifth-generation millimeter-wave mobile terminal communications, the user body blockage will significantly shadow the radiation pattern and severely affect communication performance. In this work, the antenna is moved on the mobile handset to find a suitable position to suppress the user shadow. The investigation is conducted with the user in data mode. The shadowed antenna power ratio (SAPR) and shadowed cumulative distribution function (SCDF) are used to characterize the user blockage. Both simulations with whole-body phantom and measurements with the actual user were conducted to validate the results to provide a large degree of repeatability. A significant improvement can be confirmed when moving the antenna to the top of the handset plane than the bottom. An average of 7dB in simulation and 5dB in measurement in SAPR can be improved. The proposed method can be applied in the 5G handset antenna construction to reduce the deterioration caused by the human blockage.
