Abstract: PURPOSE: A mobile phone for reducing an electronic wave absorption rate by installing an antenna therein with a space reducing structure is provided to remove or reduce a harmful electronic wave absorbed into a human body from a mobile phone body and an antenna for a user's stable and reliable use by positioning an electronic wave absorbing unit between a circuit board of the mobile phone and the antenna. CONSTITUTION: An electronic absorbing unit(16) is mounted between an antenna(17) and an internal circuit(19). The electronic absorbing unit(16) absorbs an electronic wave reflected from a rotor contact of a circuit board to reduce an influence to a resonation of the antenna(17). Thus, the antenna(17) maintains its inherent characteristics at the internal side likewise at the outer side, thereby faithfully performing its role. The electronic absorbing unit(16) absorbs even an electronic wave directing to a human body after being generated from the front side of the mobile phone(10), as well as the electronic wave generated from the antenna(17). An outer face of the bottom portion of the electronic wave absorbing unit(16) is attached on the circuit board, and side walls formed at both sides of the bottom portion have a long hole shape protruded from the surface of the circuit board. A section of the electronic wave absorbing unit(16) makes an angular U-shape. That is, the bottom portion and the side walls make 90° with each other. The antenna(17) is installed in the hole shape electronic wave absorbing unit(16). The entrance of the electronic wave absorbing unit(16) is preferably 90° to 180° centering around the antenna(17) installed in the electronic wave absorbing unit(16).

Abstract: PURPOSE: An antenna-built in mobile phone for reducing electronic wave absorption rate is provided to allow a user to stably and reliably carry a mobile phone by mounting an antenna inside the mobile phone and positioning an electronic wave absorbing unit to remove or at least considerably reduce the amount of a harmful electronic wave absorbed to a human body from the mobile phone body and the antenna. CONSTITUTION: An electronic wave absorbing unit(16) is installed between an antenna(17) and an internal circuit(19). The electronic wave absorbing unit(16) absorbs an electronic wave reflected from a conductor plate constituting the circuit board(19), to thereby reduce influence to a resonation of the antenna(17). Thus, the antenna(17) maintains its intrinsic characteristics even inside the mobile phone(10), thereby faithfully playing its role. The electronic wave absorbing unit(16) absorbs even an electronic wave directing to a human body after being generated from a front side of the mobile phone(10). Thus, an amount of electronic wave radiated while the user carries the mobile phone, that is, an SAR(specific absorption rate), can be remarkably reduced.
