Problems solved by technology
Although the physical composition of the antenna is relatively simple, its design and construction are complex, involving all aspects of the internal environment of the mobile phone, and many factors need to be considered
[0003] In mobile phone antenna design, conventional IFA (Inverted-F antenna, namely inverted F antenna) or PIFA antenna usually has one side of the head hand (left hand or right hand) with much worse performance than the other side, and the performance cannot be guaranteed. Especially when the antenna is installed close to the side of the terminal, the performance of the mid-high frequency antenna is easily affected by the occlusion of the hand. Therefore, it is necessary to find a better antenna routing design so that both left and right hands can have a good Antenna performance

Embodiment 1
[0051] refer to figure 1 and figure 2 As shown, the antenna with a parasitic module in this embodiment includes a feed point 4, and the feed point 4 is located on one side of the support 1 (the first side 11 on the right side). About 10mm away from the feed point 4, there is a ground point 5. The ground point 5 and the feed point 4 are connected to the main antenna line 2 at the same time.
[0052] The wiring main body 21 comes out from the antenna feed point 4 and generally connects three branches. The first branch 22, after connecting the main body 21, runs in the direction of the grounding point 5, and after connecting the grounding point 5, continues to route to the other side of the bracket 1 (the second side 12 on the left), at two-thirds of the bracket 1 , the wires are bent toward the end face of support 1, and run along the end face of support 1 to the edge of support 1. The overall wiring width of the first branch 22 is relatively wide, and the overall width is ...

The invention discloses an antenna with a parasitic module and a mobile terminal. The antenna with the parasitic module comprises a main antenna trace and the parasitic module, a feed point and a grounding point; an antenna support includes a first side and a second side arranged oppositely, and the feed point is arranged adjacent to the first side; the main antenna trace includes a body connecting the feed point and a first branch, a second branch, and a third branch connecting the body; all of the first branch, the second branch, and the third branch extend from the first side to the secondside, and the extension length of the second branch is between the extension lengths of the first branch and the third branch; the first branch, the second branch, and the third branch are separatelyused for implementing the first antenna performance, the second antenna performance, and the third antenna performance; the grounding point is arranged at one side of the feed point with an interval and connected to the first branch; the parasitic module includes a first parasitic unit and a second parasitic unit on both sides of the feed point; and the first parasitic unit and the second parasitic unit are both close to the main antenna trace for coupling with the main antenna trace to realize the antenna performance. The purpose of the invention is to obtain good antenna performance.
Description
technical field [0001] The invention relates to the technical field of antennas, in particular to an antenna with a parasitic module and a mobile terminal. Background technique [0002] An antenna is a device that receives and sends signals (electromagnetic waves), and is the most critical part of wireless communication. Although the physical structure of the antenna is relatively simple, its design and structure are complex, involving all aspects of the internal environment of the mobile phone, and many factors need to be considered. [0003] In mobile phone antenna design, conventional IFA (Inverted-F antenna, namely inverted F antenna) or PIFA antenna usually has one side of the head hand (left hand or right hand) with much worse performance than the other side, and the performance cannot be guaranteed. Especially when the antenna is installed close to the side of the terminal, the performance of the mid-high frequency antenna is easily affected by the occlusion of the h...
