The corners of thebezel 521 are afirst corner 5205, asecond corner 5206, a third corner 5307 and afourth corner 5208 of thesecond substrate 520, respectively.

In some embodiments, theantenna structure 530 may have one, two, three, or more.

For example, theantenna structure 530 may specifically include afirst antenna structure 531. Thefirst antenna structure 531 is disposed on the outer surface of the top and/or bottom edges (i.e., thetop portions 5201 and/or 5202) such that thefirst antenna structure 531 is located between two adjacent corner portions (i.e., between thecorner portions 5205 and 5206 and/or between thecorner portion 5207 and the corner portion 208). Thefirst antenna structure 531 may be used as a diversity antenna or a main diversity antenna.

In some embodiments, thefirst antenna structure 531 may extend along the outer surface of the top and/or bottom edge to a corner location, with thefirst antenna structure 531 terminating at the corner location.

Meanwhile, the antenna structure is prevented from being arranged at the corner part, and the possibility of bulging and cracking of the antenna structure is reduced.

In some embodiments, theantenna structure 530 may further include asecond antenna structure 532, thesecond antenna structure 532 being disposed on an outer surface of the first and/or second side of the bezel 521 (i.e., thefirst side 5203 and/or the second side 5204) such that thesecond antenna structure 532 is located between two adjacent corners (i.e., between thecorners 5205 and 5207 and/or between thecorner 5206 and the corner 208).

For example, thesecond antenna structure 532 may be disposed only on thefirst side 5203. Specifically, thesecond antenna structure 532 may be disposed on a portion of the outer surface of thefirst side portion 5203. In addition, thesecond antenna structure 532 may also extend from one end of thefirst side portion 5203 to the other end to cover the outer surface of thefirst side portion 5203, so as to enhance the radiation intensity of the antenna, so that thesecond antenna structure 532 may be used as a Global Positioning System (GPS) antenna, thereby enhancing the accuracy of Positioning.

In addition, asecond antenna structure 532 may also be provided on thesecond side 5203 for use as an additional functional antenna. For example, thesecond antenna structure 532 may have two feeding structures, and may form two radiators to receive and transmit signals in different frequency bands, where the two radiators formed by thesecond antenna structure 532 are both used as diversity antennas, or both used as main set antennas, or one used as main set antennas and one used as diversity antennas.

Thesecond antenna structure 532 may further be arranged directly on the function keys. Short-range communication signals can be transmitted and received.

As described above, by disposing theantenna structure 530 on the side of theframe 521, the length of theantenna structure 530 can be increased, so as to improve the radiation intensity of theantenna structure 530; in addition, theantenna structure 530 is not disposed at the corner portion, so that the possibility of theantenna structure 530 being bulged or cracked can be reduced.

It can be appreciated that theantenna structure 530 is disposed on the outer surface of theframe 521, and may be easily touched, and when being hit or collided by a large force, the antenna structure may be swelled, which may affect the performance of the antenna. To achieve protection of theantenna structure 530, one, two, or more layers of paint may be sprayed on the outer surface of theantenna structure 530. Of course, one, two or more layers of paint may be sprayed on the outer surface of the perimeter of theframe 521 after theantenna structure 530 is mounted thereon.

It should be noted that the protection scheme implemented for theantenna structure 530 is not limited thereto. Such as: a groove is formed on theframe 521. Specifically, with continued reference to fig. 7, theframe 521 is recessed from the outer periphery toward the outer surface toward the inner surface of theframe 521 to form a platform structure, and theantenna structure 530 is disposed in the platform structure. For example, taking the bottom side of theframe 521 as an example, the top side is recessed from the outer surface of theframe 521 toward the inner surface of theframe 521 to form a platform structure as thefirst groove 5211, and theantenna structure 531 is disposed on the platform structure. In addition, a platform structure may be disposed on the bottom side, the first side, and the second side for placing theantenna structure 530.

In some embodiments, each of the docking structures may be shaped and sized to fit the antenna structure such that the antenna structure is mounted to the docking structure with a surface of the antenna structure flush with a surface of thebezel 521.

As can be seen from the above, theantenna structure 530 is mounted on the platform structure of theframe 521 to prevent theantenna structure 530 from protruding out of the peripheral outer surface of theframe 521, so that the outer surface of theantenna structure 530 and the outer surface of theframe 521 can be flush with each other, thereby reducing the possibility of damage to theantenna structure 530.

To further enhance protection of theantenna structure 530. In some other embodiments, theantenna assembly 500 may further include aprotection member 540 made of a non-metal material, and theprotection member 540 may be made of a plastic material. Theprotection member 540 may be disposed on the outer surface of theframe 521 and the outer surface of theantenna structure 530 to cover theantenna structure 530. Such that theantenna structure 530 is located between theprotection member 540 and thebezel 521.
