Abstract:
An antenna device of a mobile terminal for securing a performance of an antenna of the mobile terminal having a case of a metal material is provided. The antenna device of the mobile terminal includes an antenna module for radiating electric waves, and a case for forming an external form of the mobile terminal, made of a metal material, having a slot in a portion of the metal material, and electrically connected to each of the antenna module and a ground of the mobile terminal, and for operating as a radiator through the slot.
Abstract:
An antenna of a mobile includes at least two internal antennas and a printed circuit board disposed between a front cover and a rear cover. The printed circuit board includes at least one first antenna mounted on an upper surface and the printed circuit board having at least one fastening opening therein. A second antenna is mounted in an upper portion of a side surface of the printed circuit board and included a protruded portion of one end protruded from a body and in which the protruded portion is fastened to the fastening opening to be fastened to a side surface of the printed circuit board and the mobile terminal can be produced having a reduced thickness.
Abstract:
An antenna using a slot formed by assembling a mobile terminal case and a metal structure (e.g., a bracket), is disclosed. The antenna reduces deterioration of antenna performance resulting from frequency interference or electromagnetic interference. The antenna can be used in various frequency bands.
Abstract:
An antenna for a camera, comprising a camera having a communication module provided therein, a first radiator provided in a predetermined position of a lens barrel of the camera and having a length and a width for receiving a signal from a first wireless communication system, a power feeding line configured to feed a power from the communication module of the camera to the first radiator, and a ground line configured to ground the first radiator.
Abstract:
A method and apparatus for measuring an antenna performance includes obtaining a voice signal received or transmitted through an antenna and corresponding to an original voice signal, quantifying the antenna performance to generate a quantification result by performing a quantification method based on the original voice signal and the obtained voice signal, and displaying the quantification result.
