Abstract

The invention discloses a multi-band smart phone antenna based on an integral metal frame. According to the multi-band smart phone antenna, no large area of space of a circuit board can be occupied while coverage of a wide band is achieved under the condition that integrity of the metal frame of a mobile phone is ensured. The multi-band smart phone antenna directly feeds electricity back to the integral metal frame through a feed piece, the integral metal frame is connected with a metal floor through a grounding piece, and therefore a first communication route and a second communication route can be formed, and finally the double-loop antenna is formed. The first communication route and the second communication route can generate low resonant frequencies to cover two low-frequency stages GSM850/990 respectively. In addition, the first communication route and the second communication route can generate a plurality of high-order resonance modes, and therefore coverage of high-frequency stages DCS/PCS/UMTS2100/LTE2300/2500 can be achieved, and coverage of wide bands is achieved. Meanwhile, integrity of the metal frame is ensured due to the design; the structure is simple; antenna tuning is easy; no large area of space of the circuit board can be occupied; the multi-band smart phone antenna is suitable for application and popularization in the technical field of terminal antennas.

Description

technical field [0001] The invention relates to the technical field of terminal antennas, in particular to a multi-band smartphone antenna based on a complete metal frame. Background technique [0002] The metal frame of the smart phone can effectively protect the smart phone, increase the mechanical strength of the smart phone, and make the appearance of the smart phone more fashionable and beautiful. However, a complete metal frame will greatly reduce the radiation performance of mobile phone antennas. It is difficult for antennas designed based on traditional mobile phone platforms to meet the requirements of their characteristics in the environment of metal frames. Therefore, the design of mobile phone antennas with complete metal frames has become the mobile phone manufacturer. A big problem. [0003] At present, in order to reduce or avoid the influence of the metal frame on the radiation performance of the mobile phone antenna, the metal frame is usually divided into...
