Problems solved by technology
The above-mentioned technology has the following disadvantages: 1. The slit and grounding destroy the continuity of the metal frame and affect the overall aesthetics of the mobile phone. At the same time, the space required for the antenna design is larger than that required by the traditional antenna; 2. Part of the metal frame is used as an antenna. part of radiation
When hands or other conductors hold the seam on the frame, the performance of the antenna will deteriorate sharply, resulting in poor transmission and reception
Third, the planar slot antenna fed by microstrip line is used for design, but the space occupied is too large to have practical application value

The invention discloses a seven-band smart phone antenna based on a full metal frame that occupies less space. The antenna feeds the first coupling radiation slot and the second coupling radiation slot through the feeding unit, and adjusts the width and length of the first coupling radiation slot and the second coupling radiation slot and the first grounding sheet, the second grounding sheet, the second The position of the four ground plates can obtain the required wide frequency bands (824-960MHZ and 1690-2690MHZ) to cover the seven frequency bands required by the terminal antenna, through the first ground plate, the second ground plate, the third ground plate, the The position of the four ground plates is optimally designed, and the gap formed by the distance between the metal frame and the metal ground is used to increase the size of the radiation gap, which greatly reduces the space occupied by the planar slot antenna of the microstrip feeder, and realizes seven antennas in a very small space. frequency smartphone antenna design. It is suitable for popularization and application in the field of terminal antenna technology.
Description
technical field [0001] The invention relates to the technical field of terminal antennas, in particular to a seven-band smart phone antenna based on a full metal frame. Background technique [0002] The metal frame makes the mobile phone full of metal texture and can increase the structural strength of the mobile phone, so many mobile phone manufacturers are very fond of using the metal frame to increase the appearance of the mobile phone. However, the metal frame has a great impact on the radiation performance of mobile phone antennas. Traditional mobile phone antenna designs are difficult to meet the application requirements of metal frame mobile phones. Therefore, mobile phones with metal frames have become a major problem for mobile phone manufacturers. [0003] At present, in order to eliminate the influence of the metal frame on the performance of the antenna, the mobile phone with the metal frame generally adopts the following methods: 1. Slit and ground the metal fra...
