The invention discloses a manufacturing method for improving the efficiency of an all-metal mobile phone three-section type antenna, and relates to the technical field of all-metal mobile phone antennas. For an all-metal mobile phone three-section type antenna, a three-section type metal back shell is connected together through in-die nanometer injection molding, and feeding points, grounding points and spring contact pints of a main antenna and an auxiliary antenna are arranged on the three-section type metal back shell, wherein the spring contact points are used for connecting capacitors, inductance tuning modules and RF switch modules. According to the manufacturing method, a plurality of vertical gaps are cut on edges of the upper and lower ends of a front shell metal medium plate, thereby blocking an eddy current loop, reducing heat loss, and eddy current loss is converted into effective electromagnetic radiation, thereby improving the antenna efficiency, and an appearance characteristic of a whole device is not changed.
Description
technical field [0001] The invention relates to the technical field of antennas in wireless communication terminal equipment, in particular to a manufacturing method for improving the efficiency of a three-segment antenna for an all-metal mobile phone. Background technique [0002] Smartphones, PDAs, mobile PCs and other mobile terminals are hereinafter collectively referred to as "mobile phones". The metal case represents an important direction of innovation in the appearance of mobile phones. The mobile phone with the metal case is hereinafter referred to as "metal mobile phone". cell phone". At present, all-metal mobile phones generally use a three-segment antenna, that is, a slit is cut at the upper and lower ends of the metal back shell, and the three metal segments of the back shell are connected into one through in-mold injection molding. All-metal mobile phones have a unique luster and texture, and are increasingly favored by consumers. However, the existing three...
