Problems solved by technology

Therefore, when the opening and closing angles of the screen and the base are different, the transmitting and receiving characteristics of the antenna will also change, such as the center frequency of the antenna transmitting and receiving signals, the radiation frequency, or the directivity and other characteristics, and thus the performance of the antenna transmitting and receiving signals will be reduced.

Abstract

An electronic device includes a first main body, a second main body, a sensing unit, and a processing unit. The second main body, including an antenna and a matching unit, is disposed on the first main body and is adapted for being opened or closed relative to the first main body. The sensing unit is disposed between the first main body and the second main body, is adapted for detecting a distance between the first main body and the second main body, and generates a control signal according to the distance, wherein the distance includes an angle and an open / close state between the first and the second main bodies. The processing unit is electrically connected to the sensing unit and the matching unit, and adjusts the matching unit according to the received control signal.

Description

technical field [0001] The present invention relates to an electronic device, and in particular to an antenna of the electronic device and an antenna adjustment method thereof. Background technique [0002] Generally speaking, antennas of traditional portable electronic devices such as notebook computers (Notebook) are arranged above the screen, and the angle between the screen and the base will not affect the performance of the antenna for receiving wireless signals. However, due to the development of technology in recent years, there are more and more design-oriented products such as ultra books, and there are more and more portable electronic devices with metal shell designs. When the notebook computer is designed with a metal case, the antenna of the notebook computer must be moved to the base, near the rotating shaft at the junction of the keyboard and the screen. Therefore, when the opening and closing angles of the screen and the base are different, the transmitting ...
