electronic device with antenna

Abstract

An electronic device with an antenna provided by the invention comprises a first metal housing having a first side edge; a second metal housing having a second side edge; a first rotating shaft connected between the first side edge and the second side edge; a second rotating shaft connected between the first side edge and the second side edge; a grounding connection portion connected with the first and second side edges, wherein the first rotating shaft, the first metal housing, the grounding connection portion and the second metal housing form a first closed-groove antenna structure; a first antenna unit having a first radiation portion, a first low-frequency feed end and a first grounding end; and a first controllable capacitor connection portion having a first end and a second end, wherein there is a first controllable capacitance value between the first and second ends, the first end is connected with the first side edge, the second end is connected with the second side edge, and the first controllable capacitance value is controlled by the control unit. The space occupied by the antenna is reduced without losing the function of switching operation frequency of a wireless wide area network and the application function of a wireless area network or WiFi, and the interference on the position arrangement of the antenna is not generated.

Description

Technical field [0001] The invention belongs to the technical field of electronic products, and specifically relates to an electronic device with an antenna. Background technique [0002] Portability is an important factor when considering electronic devices with wireless communication functions or wireless networking (wireless Internet access) functions. For example, a laptop computer is a portable electronic device. [0003] figure 1 Shown is a schematic diagram of a laptop computer in the category of electronic devices in the prior art, which includes an upper cover 10 with a screen, a lower cover 30 as the main body of the computer, and a shaft 20 for connecting the upper cover 10 and the lower cover 30. With the development of wireless networks, notebook computers in the prior art are also developing in the direction of combining wireless network functions, and the commonly used built-in (also called built-in) antennas are required to keep the appearance as simple as possible,...

Problems solved by technology

However, in order to make the appearance of the notebook computer more eye-catching, the manufacturer of the notebook computer often greatly reduces (shrinks) the screen frame of the upper cover 10, so that the position of the antenna is greatly restricted, so the same wireless communication quality or even Under the condition of requiring higher wireless transmission performance, it is undoubtedly a challenge for the antenna designer of the notebook computer. The technical solution to be introduced below is produced under this background
