Abstract

An antenna device comprising: a ground conductor; a radiating conductor having a feed point; and a protective conductor, insulated from the ground conductor and arranged at a position that is, in a form of use, closer to a specific point of the user than the radiating conductor and is A position such that at least a portion of the protective conductor overlaps a location where the intensity of the electric field radiated from the radiation conductor is high.

Description

technical field [0001] The present disclosure relates to antenna devices. Background technique [0002] In recent years, various electronic devices, such as mobile phones, tablet terminals, and mobile game machines, have begun to be equipped with wireless communication functions. Since these devices are placed close to the human body in telephone calls and data transfers, attention has been paid to the influence of radio waves on the human body. In Japan, in consideration of this concern, the specific absorption rate (SAR), which is the amount of energy absorbed by the human body, is defined by the law on radio waves radiated by mobile phones and the like. [0003] SAR is an average of the amount of energy absorbed by a unit mass of a human body per unit time, and two standards (whole body SAR and local SAR) are defined. SAR is defined by the following calculation formula. [0004] SAR=σ|E|2 / ρ [0005] E: electric field strength [V / M] [0006] σ: Conductivity of human t...
