ABSTRACT:
An antenna structure for a mobile phone to improve its hearing aid compatibility (HAC) character by metal obscuring, the antenna structure mainly is composed of an antenna base board and a copper foil; the antenna base board is provided in a housing of the mobile phone near a sound outputting hole, and a metallic thin layer is made in the housing of the mobile phone in corresponding by position with the antenna base board, the ground surface between the metallic thin layer and a circuit board in the housing of the mobile phone will form an electrically conductive connection. With this structure, distribution of the strength of the electric field of the antenna structure will be improved; thereby the test results for HAC near the sound outputting hole can be evidently improved.
