BATTERY MODULE OF A MOBILE TERMINAL FOR PREVENTING FAILURE DUE TO ELECTROMAGNETIC WAVE, CONCERNED WITH RESOLVING VARIOUS FAILURES, OPTIMIZING CHARACTERISTICS OF AN ELECTRONIC CHIP ANTENNA AND REDUCING A SPECIFIC ABSORPTION RATE

摘要

PURPOSE: A battery module of a mobile terminal for preventing failure due to electromagnetic wave is provided to resolve various failures, optimize characteristics of an electronic chip antenna and reduce an SAR(Specific Absorption Rate) by using an electronic wave shielding thin sheet. CONSTITUTION: A housing(10) includes a coupling part at one end so as to be detachably attached to a front or rear side of a mobile terminal and a charging terminal(40) for supplying power to the terminal formed exposed at the other end. A battery pack(20) is detachably attached in the housing(10) to supply power to the mobile terminal. An electronic chip antenna(30) is installed to face the battery pack(20) inside the housing(10) and communicates with an external electronic chip recognizing unit. Both ends of the electronic chip antenna(30) are connected to the charging terminal(40). A thin sheet(50) is interposed between the battery pack(20) and the electronic chip antenna(30), with its surface and rear side in contact with the battery pack(20) and the electronic chip antenna(30), which enhances directionality of the electronic chip antenna(30).
