Metal terminal back cover and terminal

Abstract

The present invention discloses a metal terminal back cover and a terminal, the metal terminal back cover comprises a base plate, the base plate is provided with at least one micro-seam tape, the micro-seam tape is provided with a plurality of micro-seams, the at least one micro-seam tape separates the base plate from at least two radiation parts, the at least two radiation parts wherein at least one for access to the matching circuit, and emit electromagnetic waves. The use of the micro-slit tape is provided with a plurality of micro-slits, thereby reducing the proportion of the non-metallic part of the metal terminal cover; And the use of at least one radiation portion connected to the matching circuit to achieve radiated electromagnetic waves; Thus the metal terminal cover itself to achieve antenna RF, thereby improving the antenna RF efficiency, and then in order to ensure the overall appearance of the terminal requirements, but also improve the antenna RF efficiency, to achieve the effect of improving the user experience.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a metal terminal back cover and a terminal. Background technique [0002] At present, the metal back cover of the mobile phone is usually provided with two plastic isolation strips to separate the metal back cover into three metal parts, so that the radio frequency efficiency of the antenna inside the mobile phone can be improved by utilizing the gap between the metal parts. However, as users have higher and higher requirements for the appearance of mobile phones, the proportion of the metal part of the metal back cover of the mobile phone is required to increase, resulting in a decrease in the proportion of the plastic isolation belt. In this case, as the proportion of the plastic isolation strip decreases, the radio frequency efficiency of the antenna inside the mobile phone will decrease, thereby affecting the user experience of the mobile phone. Contents of the invention...
