Abstract
Systems, methods, and devices for reducing specific absorption rate (SAR) for an antenna are disclosed. An example method includes determining a location of a hotspot on a surface of the antenna, the hotspot comprising an area of increased SAR above a predetermined limit. The method further includes introducing a recess in the surface of the antenna at a recess location, the recess location based on the location and frequency characteristics of the hotspot. Example systems and devices include a surface forming an antenna structure and a recess in the surface of the antenna at a recess location, wherein the recess location would be a hotspot when the surface of the antenna is not recessed, the hotspot comprising an area of increased SAR above a predetermined limit.
