Abstract

Disclosed is an internal antenna using electromagnetic coupling supporting improved impedance matching. The disclosed antenna comprises: a first electrically conductive member of which one terminal is electrically connected to an electrical power point; a second electrically conductive member which is electrically connected to the earth at a predetermined distance from the first electrically conductive member; an emitter which extends from the second electrically conductive member; and an earthing plate which is coupled to the other terminal of the first electrically conductive member. The disclosed antenna has the advantage that impedance matching characteristics can be improved while ensuring appropriate broadband characteristics and multi-band characteristics.

Description

[0001] technology area [0002] The invention relates to a built-in antenna, in particular to a wide-band built-in antenna utilizing electromagnetic coupling. Background technique [0003] At present, along with miniaturization and weight reduction of mobile communication terminal equipment, ultra-thin structures are also required. Compared with the continuous demand for miniaturization, the functions of mobile communication terminal equipment need to be more and more diversified. [0004] Therefore, with the miniaturization and multi-functionalization of mobile communication terminal equipment, it is necessary to minimize the space occupied by the antenna in the mobile communication terminal equipment, thus, the requirements for the design of the antenna are also raised. [0005] Moreover, the current mobile communication terminal equipment is showing a trend towards a converged terminal equipment capable of accommodating various frequency bands in one terminal equipment. Th...
