Embodiment Construction

[0027] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] The antenna is a necessary and important device in the wireless mobile communication system. It performs the function of energy conversion and is the link and bridge between the external space electromagnetic wave / electromagnetic field and the internal circuit of the system. At present, mobile communication terminals such as tablets and mobile phones are limited by the reserved antenna space, and the commonly used antennas are mostly PIFA antennas (that is, planar inverted F antennas) or monopole antennas, both of which are small planar antennas. Since metal devices are often arranged around the antenna, such as the metal frame of the tablet computer, the metal back cover, the metal bracket for installing the display screen, etc., these metal devices will absorb electromagnetic waves in the space, thereby reducing the radiation efficienc...

Abstract

The invention discloses a method capable of improving the efficiency of a mobile communication antenna and a mobile communication terminal. In the invention, a metal device is laid at the periphery of the mobile communication antenna, and the wavelength coverage of a radio signal received by the mobile communication antenna is represented by Lambada; if the metal devices laid at the periphery of the mobile communication antenna form a closed circuit, the circumference of the closed circuit is changed so as to avoid the range of Lambada, a half of the Lambada, or a quarter of the Lambada; if the metal device laid at the periphery of the mobile communication antenna is an insulated metal device, the size of the equivalent antenna formed by the insulated metal device is changed so as to avoid the above range; and under the situation that the radiation space of the mobile communication antenna is not affected, the mutual coupling between the mobile communication antenna and the peripheral metal device is reduced, the wastage resistance of the mobile communication antenna is reduced, the radiation efficiency of the mobile communication antenna is improved, and the receiving and emitting performances of the mobile communication terminal are optimized.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and in particular relates to a processing method proposed for improving the radiation efficiency of a mobile communication antenna and a mobile communication terminal designed using the method. Background technique [0002] Since Apple released the iPad in January 2010, tablet computers, handheld devices with large screens, entertainment functions, and mobile Internet, have gradually been accepted by the market, and have developed and eventually become the new trend of entertainment devices. Compared with mobile phones and notebook computers, two mainstream mobile devices, tablet computers have most of the functions of traditional computers, support handwriting input, support display output, have data processing and graphics processing capabilities, and are small in size and weight, strong in mobility, and convenient. Carry it with you and use it by hand for a long time. The tablet ...
