In some embodiments, the mobile terminal includes a body side enclosure, and the GPS antenna module is disposed inside the body of the mobile terminal.

The side wall of the body comprises a first side, a second side and a side edge connected with the first side and the second side, and an insulating section is arranged on the side edge.

The first edge and the second edge are short edges of the mobile terminal, and the side edges are long edges of the mobile terminal. And the first side is located at the upper part of the mobile terminal, and the second side is located at the lower part of the mobile terminal. Wherein "up" and "down" are referred to a general use orientation of the mobile terminal. Taking a mobile phone as an example, the orientation of the normally displayed image of the mobile phone is taken as a reference, or the orientation of the receiver and the microphone (the receiver is on the upper part, and the microphone is on the lower part) is taken as a reference.

The GPS antenna module is arranged inside the mobile terminal, is positioned on one side, close to the first edge, of the insulating section and is attached to the first edge.

However, with the mobile terminal in the above embodiment, the mobile terminal has the following drawbacks:

first, the performance of the GPS antenna module is poor. By adopting the setting mode of the GPS antenna module, in an energy directional diagram of the GPS antenna module, the energy of the GPS antenna module is mainly distributed on the side, so that the upper hemisphere occupation ratio is low. The upper hemisphere proportion in the energy directional diagram represents the radiation performance of the GPS antenna module, and the lower hemisphere proportion indicates that the performance of the GPS antenna module is weak. At this time, it is difficult to satisfy the precision and accuracy of positioning or navigation, which affects the user experience.

Secondly, besides the GPS antenna module, the upper portion of the mobile terminal is further provided with other functional modules, such as a camera module, a structured light module, a handset module, and the like. Therefore, the arrangement mode in the embodiment occupies the upper space of the mobile terminal, and increases the difficulty in planning the internal space of the mobile terminal.

Based on the above situation, the embodiments of the present disclosure provide a mobile terminal to solve the above technical defects. Fig. 1 to 3 are schematic structural diagrams of a mobile terminal shown according to various exemplary embodiments. Fig. 4 and 5 illustrate energy patterns of a GPS antenna module in a mobile terminal according to various exemplary embodiments. In the embodiments of the present disclosure, the kind of the mobile terminal is not specifically limited, and the mobile terminal includes but is not limited to: the mobile phone, the tablet computer, the intelligent wearable device (such as intelligent watch, intelligent bracelet), the mobile device, and the medical equipment. In the drawings, only a mobile phone is taken as an example for illustration.

As shown in fig. 1, the mobile terminal includes a body side 100. The body side gusset 100 includes first and second oppositely disposed

sides

110 and 120, and side edges 130 connected to the first and

second sides

110 and 120, respectively. The lengths of the first edge 110 and the second edge 120 are less than the length of the side edge 130, the first edge 110 is located at the upper part of the mobile terminal, and the second edge 120 is located at the lower part of the mobile terminal.

Also, the mobile terminal includes two sides, and the side 130 refers to any one of the two sides in the embodiment of the present disclosure.

The side 130 includes: first conductive segment 131, insulating segment 132 connected to first conductive segment 131, and second conductive segment 133 connected to insulating segment 132. Wherein the end of first conductive segment 131 not connected to insulating segment 132 is connected to first side 110 and the end of second conductive segment 133 not connected to insulating segment 132 is connected to second side 120. Optionally, the length of first conductive segment 131 is less than the length of second conductive segment 133.

First conductive segment 131, second conductive segment 133, first side 110, and second side 120 are all fabricated from a conductive material (e.g., aluminum, stainless steel, steel aluminum composite, titanium alloy, etc.). The insulating segment 132 is made of an insulating material (e.g., ceramic, resin, glass, etc.). In view of the above, avoid fuselage side wall 100 to produce the shielding effect to GPS antenna module through setting up insulating section 132, ensure antenna module normal use. Also, the length dimension of the insulating segment 132 is not particularly limited, for example, 4mm, 5mm, 6mm, 7mm, etc.

The mobile terminal further includes a GPS antenna module 200 disposed inside the body. In the embodiment of the present disclosure, specific types of the GPS antenna module 200 may be selected as follows:

alternatively, the GPS antenna module 200 is used only for receiving GPS signals.

Alternatively, the GPS antenna module 200 is a combined antenna module. For example, the combo antenna module (combo antenna module) may also be used as a Wifi (a wireless local area network technology based on IEEE 802.11 standard) antenna by enabling a communication connection with an external device for Wifi.

In such an alternative, the operating frequency of the combined antenna module when used as a GPS antenna is 1575MHz. The working frequency of the combined antenna module used as a Wifi antenna is 2400 MHz-2500 MHz and 5200 MHz-5800 MHz.

Inside the mobile terminal body, the GPS antenna module 200 is disposed along the side 130. In one embodiment, as shown in fig. 2, the GPS antenna module 200 is disposed against an inner wall of the side 130. In this way, a complete clearance area is conveniently constructed for the GPS antenna module 200, and normal use of the GPS antenna module 200 is ensured. In addition, the adoption of the mode also avoids occupying the central space in the body of the mobile terminal, and reduces the difficulty of planning the internal space of the mobile terminal.

Optionally, the GPS antenna module 200 extends from the second conductive segment 133 to the first conductive segment 131. In this way, the length requirement of the GPS antenna module 200 is satisfied, and the desired radiation efficiency of the GPS antenna module 200 is achieved. Furthermore, the GPS antenna module 200 spans the insulation section 132, thereby increasing the upper hemispherical ratio of the energy pattern of the GPS antenna module 200.

Further, the GPS antenna module 200 extends from the first conductive segment 131 of the side 130 to the first edge 110.

In this way, the length of the GPS antenna module 200 is increased, and the length of the GPS antenna module 200 is proportional to the radiation power, so as to increase the radiation power of the GPS antenna module 200 and optimize the antenna performance. In addition, the GPS antenna module 200 is disposed along the joint of the side 130 and the first side 110, so as to improve the utilization rate of the internal space of the mobile terminal and optimize the structural integrity of the mobile terminal.

As shown in fig. 2, the GPS antenna module 200 includes a feeding point 210. The feeding point 210 is located at a side of the insulating segment 132 close to the second side 120 in the length direction of the side 130, i.e. the feeding point 210 is located at a position corresponding to the second conductive segment 132.

Since first conductive segment 131 is connected to first edge 110, insulating segment 132 is closer to the bending region where first conductive segment 131 meets first edge 110. In this case, the feeding point 210 is disposed corresponding to the second conductive segment 132, so as to weaken the influence of the bending region formed by connecting the side edge 130 and the first edge 110 on the antenna performance, and improve the upper hemisphere proportion of the GPS antenna module 200.

And, along the length direction of the side 130, the distance from the feeding point 210 to the edge of the insulating segment 132 close to the second side 120 is 3-15 mm, for example, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, etc. In this manner, the feed point 210 is disposed near the insulative segment 132, further optimizing GPS antenna module 200 performance.

The GPS antenna module 200 further includes a feed line connected to the feed point 210. When the GPS antenna module 200 is disposed along the side 130, the feeding line 220 and the first side 110 form a small angle (e.g., 5 °, 10 °, 15 °, 20 °, etc.). In such a case, the electric field excited by the feed line is approximately parallel to the first side 110. When a user normally holds the mobile terminal, the electric field excited by the feed line is approximately parallel to the horizontal direction. At this time, the radiation energy of the GPS antenna module 200 is concentrated and distributed on the upper hemisphere of the energy pattern, so as to further optimize the performance of the GPS antenna module.

In particular, the feeding line connected to the feeding point 210 is disposed along the length direction of the first side 110, i.e., the feeding line is disposed parallel to the first side 110. In this case, the GPS antenna module 200 has a higher upper hemispherical ratio, and the performance of the antenna module is better.

In one embodiment, as shown in fig. 2, GPS antenna module 200 further includes a feedpoint 220. The feed point 220 is located on the side of the insulating section 132 adjacent to the first side 110 in the length direction of the side 130. In this way, the ground point 220 and the feeder line connected to the ground point 220 avoid a functional module located in a central region in the body of the mobile terminal, and avoid causing mutual interference.

Further, as shown in fig. 3, the ground feeding point 220 is disposed at a portion where the GPS antenna module 200 extends to the first side 110. Generally, a camera module 300 is disposed in the mobile terminal, and the camera module 300 is disposed near a bending region formed by the connection between the first edge 110 and the first conductive segment 131. In this case, compared with the position where the GPS antenna module 200 corresponds to the first conductive segment 131, the feed point 220 is disposed at the position where the GPS antenna module 200 corresponds to the first edge 110, and the feed point 220 and the feed distance are far from the camera module 300, so that the camera module 300 is effectively avoided, and the mutual interference between the two is avoided.

The mobile terminal provided by the embodiment of the disclosure has the advantage that the upper hemisphere proportion of the energy directional diagram of the GPS antenna module is high, and the GPS antenna module 200 is high in efficiency and good in performance. The performance of the GPS antenna module will be described below with the aid of a specific performance detection diagram.

Fig. 4 is an energy pattern of the GPS antenna module in the mobile terminal shown in fig. 1 to 3, and fig. 5 is an energy pattern of the GPS antenna module when the GPS antenna module is disposed along the first side. The frequency of the performance test of the GPS antenna module shown in fig. 4 and 5 is 1.575GHz. As can be seen from comparing fig. 4 and fig. 5, the energy of the GPS antenna module 200 in fig. 4 is concentrated in the upper hemisphere, and the energy of the upper hemisphere of the GPS antenna module in fig. 5 is significantly lower than the energy of the upper hemisphere in fig. 4. Therefore, the scheme provided by the embodiment of the disclosure indeed optimizes the performance of the GPS antenna module in the mobile terminal.

Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein. This application is intended to cover any variations, uses, or adaptations of the disclosure following, in general, the principles of the disclosure and including such departures from the present disclosure as come within known or customary practice within the art to which the disclosure pertains.
