Embodiment Construction

[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, specific embodiments will be described in detail below with reference to the accompanying drawings.

[0044] A slot antenna is an antenna formed by a slot in a metal surface. The narrow slot opened on the ideal conductive plate is the dual form of the dipole antenna, so the length of the slot antenna is the same as that of the dipole, which is λ / 2. The slot antenna can be fed asymmetrically by the coaxial line, the outer conductor of the coaxial line is connected to the metal plate, and the inner conductor is connected to the other side of the slot, such as figure 1 shown. For slots on a finite conductive surface, the influence of edge diffraction must be considered. Therefore, the design of the slot antenna on the notebook case must be combined with the actual application environment for co-simulation.

Abstract

The invention provides mobile electronic equipment, which comprises a shell, a slot antenna and a communication module, wherein the shell at least comprises a first part of a metal material; the first part at least comprises a first metal surface and a second metal surface which are connected with each other; the slot antenna is engraved on the first part and used for radiating a signal and comprises a first resonance branch provided with a feedback point; the first resonance branch comprises a main body and a tail; the main body is engraved on the first metal surface; the tail extends to the second metal surface from the main body and hollows out of the second metal surface; the first resonance branch forms a 1 / 4-wavelength slot antenna and corresponds to a first resonance point; and the communication module is connected with the slot antenna through coaxial cables at the feedback point and used for supplying the signal. According to the mobile electronic equipment, the problem about implementation of the antenna of the mobile equipment with the full metal shell is solved; and the size of a 3G antenna can be effectively reduced.

Description

technical field [0001] The invention relates to an antenna of a portable electronic device, in particular to a mobile electronic device in which a slot antenna is arranged on a full metal casing. Background technique [0002] Full metal casing notebook is the goal that many notebook manufacturers have been pursuing for a long time. The current metal casing notebooks all adopt a two-piece structure, that is, the part outside the antenna area is made of metal materials, and the antenna area installed for wireless communication is made of plastic materials. Such a solution is not only complicated to process, expensive, and not easy ID (industrial) design affects the overall appearance. [0003] Some technologies propose to slot a metal casing to implement a slot antenna, and provide an antenna structure satisfying WLAN (Wireless Local Area Network, wireless local area network) communication. But for the 3G (third generation communication technology) antenna, due to its low op...
