Embodiment Construction

[0019] The present invention will be further described below in conjunction with the examples, but not as a limitation of the present invention.

[0020] Please combine figure 1 and figure 2 , the specific structure of the double-layer coupled broadband mobile phone antenna of the present embodiment is such that it includes the first resonant unit 1, the second resonant unit 2, the third resonant unit 3 and the vertical connecting portion 5 A signal feed point 6 and a ground feed point 7 connected to the first resonance unit 1 , the second resonance unit 2 and the third resonance unit 3 .

[0021] The first resonant unit 1 is a C-shaped structure with an open slot 11 formed by extending the vertical connecting portion 5 to the left in a plane perpendicular thereto. The upper side 12 of the C-shaped structure is connected to the vertical connecting portion 5 , and a gap 8 is formed between the lower side 13 of the C-shaped structure and the vertical connecting portion 5 , an...

Abstract

The invention discloses a double-layer coupling broadband mobile phone antenna. The double-layer coupling broadband mobile phone antenna includes a first resonance unit, a second resonance unit, a third resonance unit, a signal feed point, a ground feed point and a fourth resonance unit, wherein the signal feed point and the ground feed point are connected with the first resonance unit, the second resonance unit and the third resonance unit through a vertical connection part, and the fourth resonance unit extends from the ground feed point; the resonance frequency of the first resonance unit is smaller than the resonance frequency of the second resonance unit, the resonance frequency of the second resonance unit is smaller than the resonance frequency of the third resonance unit, and the resonance frequency of the third resonance unit is smaller than the resonance frequency of the fourth resonance unit; the second resonance unit and the fourth resonance unit are up and down arranged in parallel and are electromagnetically coupled. The double-layer coupling broadband mobile phone antenna is processed to be arranged at the inner and outer sides of a mobile phone shell through an LDS technology, similar resonance frequency points are generated by the adoption of the mutual electromagnetic coupling effect between the two resonance units, and therefore the purpose of broadening the bandwidth of the antenna is achieved.

Description

technical field [0001] The invention relates to a mobile phone antenna, in particular to a double-layer coupled broadband mobile phone antenna, which belongs to the technical field of antennas for wireless communication. Background technique [0002] Antenna technology for wireless communication The antenna is an important part of the mobile communication system, and it undertakes the task of transmitting and receiving electromagnetic waves. The mobile phone built-in antenna is widely used in various mobile phone models due to its small size, low profile, easy processing and other advantages. However, the built-in antenna of the mobile phone is a resonant antenna, and the narrow bandwidth is its biggest defect. In the past, the manufacturing process of mobile phone antennas was mainly based on FPC and steel sheet molds, which made mobile phone antennas often single-layer antennas, which greatly limited the quality of mobile phone antennas. Design ideas. [0003] With the i...
