ANTENNA MODULE PLACEMENT AND HOUSING FOR REDUCED POWER DENSITY EXPOSURE

Abstract:

Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may use transmissions causing power density exposure (PDE) to nearby users. To reduce the PDE of an antenna module (e.g., below a maximum PDE threshold), the UE may implement a shielding strip around the antenna module. For example, the antenna module may include a substrate having a first surface and a set of antenna elements on the first surface. The shielding strip may enclose the set of antenna elements of the antenna module and extend away from the first surface above the antenna elements. The shielding strip may reduce PDE outside a field of view of the antenna module. Additionally, in some cases, the placement of the antenna module in the UE and the materials used for constructing the UE may further reduce PDE.
