Abstract:
1. A method for improving a compatibility of a hearing aid with an antenna located in a mobile phone, connecting said antenna to a grounding surface, locating at least one metal frame perpendicular to said grounding surface changing a direction of radiation of said antenna and enhancing directivity of said antenna on a side away from the hearing aid, and reducing a quantity of radiation proceeding toward said hearing aid and improving a near-field quantity (for about 3 dB) of an electric field of an HAC (hearing aid compatibility) tested plane, wherein said antenna has a metal radiating member located on a carrier plate, said radiating member and said carrier plate are parallel to and spaced apart from said grounding surface by a height of said metal frame, said metal radiating member has a grounding spot and a feed in spot extending downwardly and connected to an edge of said grounding surface; wherein said grounding spot and said feed in spot are electrically connected to an edge of said carrier plate; wherein said radiating member has two opposing edges aligning with two opposing edges of said carrier plate.
