In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in detail below with reference to the accompanying drawings. Examples of these preferred embodiments are illustrated in the accompanying drawings. The embodiments of the invention shown in the drawings and described in accordance with the drawings are exemplary only, and the invention is not limited to these embodiments.
It should be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and/or processing steps that are closely related to the solution according to the present invention are shown in the drawings, and other details that are not relevant are omitted.
Referring to fig. 1, the present embodiment provides an antenna 1 of a mobile communication terminal, where an antenna support 2 is disposed on the mobile communication terminal, the antenna 1 is disposed on the antenna support 2, and the antenna support 2 includes a top surface 21 and an adjacent side surface 22. The top surface 21 is provided with feeding points 3 and feeding points 4 arranged at intervals, as shown in fig. 2-4, and the antenna 1 includes a low-frequency routing area 11, a medium-frequency routing area 12 and a high-frequency routing area 13.
As shown in fig. 5, the low-frequency routing area 11 is disposed on the top surface 21 and extends to the side surface 22, a head end 11a of the low-frequency routing area 11 is located at the feeding point 3, and a tail end 11b of the low-frequency routing area 11 is located at a first end 22a of the side surface 22.
Referring to fig. 6, the middle frequency routing area 12 is disposed on the side surface 22, a head end 12a of the middle frequency routing area 12 is adjacent to a routing of the low frequency routing area 11 on the side surface 22, and a tail end 12b of the middle frequency routing area 12 is located at a second end 22b of the side surface 22 opposite to the first end 22 a.
As shown in fig. 7, the high-frequency routing area 13 is disposed on the top surface 21, a head end 13a of the high-frequency routing area 13 is located at the feed point 4, a tail end 13b of the high-frequency routing area 13 is adjacent to a second end 22b of the side surface 22, and the head end 13a of the high-frequency routing area 13 is provided with a connecting portion 131 extending toward the first end 22a of the side surface 22 to be connected to the low-frequency routing area 11.
In the antenna 1 of the mobile communication terminal provided in this embodiment, the low-frequency routing area 11 extends to the side surface 22 of the antenna support 2 for routing, and the medium-frequency routing area 12 is disposed along the side surface 22 of the antenna support 2, because the antenna 1 fully utilizes the space on the side surface 22 of the antenna support 2 for routing, the routing on the top surface 21 of the antenna support 2 is relatively narrow, and the antenna support 2 is correspondingly disposed at the bottom of the mobile communication terminal, the side surface 22 of the antenna support 2 is far away from the center of the internal space of the mobile communication terminal relative to the top surface 21, that is, is relatively far away from the metal-containing component inside the mobile communication terminal. Therefore, the antenna 1 is less interfered by parts with metal in the mobile communication terminal, and the antenna 1 can have a wider bandwidth and cover more frequency bands in the limited internal space of the mobile communication terminal to obtain good radiation performance.
Further, referring to fig. 1 to fig. 3, a slot 10 is formed between the low frequency routing region 11 and the high frequency routing region 13, and the slot 10 extends on the top surface 21 of the antenna support 2 along a direction from the head end 13a of the high frequency routing region 13 to the first end 22a of the side surface 22. In particular, one end of the slot 10 is located between the feed point 3 and the feed point 4. The antenna routing areas on the two sides of the slot 10 are coupled, that is, the connection portion 131 of the high-frequency routing area 13 is coupled with the routing on the top surface 21 of the low-frequency routing area 11, so that the impedance of the antenna 1 is easily matched to a range of about 50ohm, the radiation efficiency of the antenna 1 is increased, and the radiation performance of the antenna 1 is further improved.
Specifically, the width of the slot 10 is 0.4mm to 0.6 mm. In this embodiment, the width of the slot 10 is set to about 0.5mm, and the length of the slot 10 should be adjusted according to the actual impedance of the antenna 1 and the antenna trace in the corresponding area.
In this embodiment, as shown in fig. 1 and fig. 2, a tuning switch point 5 is disposed on the top surface 21 of the antenna support 2, and the intermediate frequency routing area 12 is connected to the tuning switch point 5. In a mobile communication terminal with many metal parts, the bandwidth of the intermediate frequency is generally relatively narrow due to the severe environment interference, but in the antenna provided by this embodiment, both the intermediate frequency routing area 12 and the low frequency routing area 11 can be connected to a tuning switch through the tuning switch point 5, and the tuning switch tunes the intermediate frequency band and the low frequency band, so that the intermediate frequency band and the low frequency band of the antenna 1 can obtain a wide bandwidth.
Further, the intermediate frequency wiring area 12 is respectively connected to the feeding point 3, the feeding point 4, and the tuning switch point 5, and the feeding point 3, the feeding point 4, and the tuning switch point 5 are respectively connected to different positions of the intermediate frequency wiring area 12.
In this embodiment, the feeding point 3, the feeding point 4, and the tuning switch point 5 are located on the same straight line, and the feeding point 4, the feeding point 3, and the tuning switch point 5 are sequentially disposed at the edge of the antenna 1 away from the side surface 22 at intervals. The feed point 3, the feed point 4 and the tuning switch point 5 are arranged at the edge of the low-frequency wiring area 11 far away from the side surface 22, so as to be conveniently connected with a feed source, a ground terminal and a tuning switch which are arranged in the mobile communication terminal.
The high-frequency wiring area 13 is similar to a parasitic unit, and the antenna 1 performs communication in a high-frequency band of 2300Mhz to 2700Mhz through the high-frequency wiring area 13.
In this embodiment, the antenna support 2 is preferably a part of a rear housing of the mobile communication terminal, and the routing area of the antenna 1 is not a completely regular shape, but the routing of the antenna 1 is correspondingly adjusted in terms of routing length and width according to other components on the rear housing and the shape profile of the rear housing, so that the routing of the antenna 1 in this embodiment is more suitable for the routing space provided by the actual mobile communication terminal for the antenna 1, and considering the whole, the routing of the antenna 1 on the side surface 22 of the antenna support 2 should be as full as possible of the available space. The area between the head end 12a of the intermediate frequency cabling area 12 and the trace on the side surface 22 of the low frequency cabling area 11 corresponds to a USB port disposed on the rear shell of the mobile communication terminal, and the closer the head end 12a of the intermediate frequency cabling area 12 and the trace on the side surface 22 of the low frequency cabling area 11 are disposed, the larger the intermediate frequency bandwidth of the antenna 1.
The embodiment of the invention also provides a mobile communication terminal which comprises an antenna bracket 2 and the antenna 1 arranged on the antenna bracket 2.
In summary, in the mobile communication terminal and the antenna 1 thereof provided in the embodiments of the present invention, the low frequency routing area 11 of the antenna 1 is extended to the side 22 of the antenna support 2 for routing, and the medium frequency routing area 12 is routed along the side 22 of the antenna support 2. The antenna 1 fully utilizes the space on the side surface 22 of the antenna support 2 to route, and relatively reduces the route on the top surface 21 of the antenna support 2, so that the antenna 1 is far away from a part with metal inside the mobile communication terminal, the interference on the part is reduced, the antenna 1 can cover more and wider frequency bands in the limited internal space of the mobile communication terminal, and the radiation performance of the antenna 1 is improved.
