Detailed Description
Advantages of the invention are further illustrated in the following description, taken in conjunction with the accompanying drawings and detailed description.
Referring to fig. 1, a schematic structure of a smart terminal with an antenna according to a preferred embodiment of the present invention is shown. In this embodiment, the antenna is disposed within a terminal having an all-metal cover. Specifically, the antenna is formed in a sectional manner, and is divided into a first antenna unit 10 and a second antenna unit 20, and is respectively positioned at both sides of the inside of the metal cover body and the inside of the side edge of the terminal, preferably at both corners of the same end of the inside body of the terminal. The attaching position of the antenna is different from the conventional antenna setting position, and each antenna unit includes two parts, i.e. a fixing part and an extending part, for example, the first antenna unit 10 includes a first fixing part 11 and a first extending part 12, and the second antenna unit 20 includes a second fixing part 21 and a second extending part 22. The first fixing portion 11 and the second fixing portion 21 are provided at the end of the inner body of the terminal, and may be formed through a conventional process such as FPC or LDS, thereby fixing the antenna in the terminal first. The first extension portion 12 and the second extension portion 22 extend from the first fixing portion 11 and the second fixing portion 21, respectively, and the extending direction is still along the side of the terminal, and is also attached to the side, so as to increase the forming length of the antenna. With the above configuration, the antenna serving as the first fixing portion 11 and the second fixing portion 21 can have a communication function because the antenna is formed based on the same body as the antenna, in addition to the fixing portion serving as the antenna. Meanwhile, the setting positions of the first antenna unit 10 and the second antenna unit 20 are: if the position along the end and side of the terminal is set, the part where the metal material cannot be set is also the end and side of the terminal, and the rear cover part is not touched by the position, so the cover body of the terminal can be made of all-metal material.
In addition, the segmented arrangement of the antennas does not affect the reception of their signals. Specifically, the first antenna unit 10 covers a first frequency band, the second antenna unit 20 covers a second frequency band, and after the first frequency band and the second frequency band are overlapped, the full frequency band required by the terminal can be covered. If the signal received by the terminal is in the first frequency band, the first antenna unit 10 works as a communication medium, and if the signal received by the terminal is in the second frequency band, the signal is switched to the second antenna unit 20 to work as a communication medium, so that the signal receiving and transmitting effect of the terminal is not affected. It is to be understood that the first frequency band covered by the first antenna unit 10 and the second frequency band covered by the second antenna unit 20 may have a partial overlap, and the first antenna unit 10 and the second antenna unit 20 may be applicable in the overlapping frequency bands; or the first frequency band and the second frequency band are seamlessly matched, and the first frequency band and the second frequency band are added to form a full frequency band. For example, the first frequency band includes all low frequencies and all and/or part of intermediate frequencies; the second frequency band comprises all high frequencies and all and/or part of intermediate frequencies, and intermediate frequency parts included in the two frequency bands can be repeated or continuous according to requirements.
Preferably, the first fixing portion 11 and the second fixing portion 21 are provided in a ring shape in order to ensure that the structural arrangement of the antenna is not affected in the above-described embodiment, since the signal reception of the antenna is related to its own length. Specifically, the end of the terminal may be regarded as a cuboid, the first fixing portion 11 and the second fixing portion 21 are wound on the surface of the cuboid, the first fixing portion 11 is disposed on the left side of the end face of the cuboid, the second fixing portion 21 is disposed on the right side of the end face of the cuboid, and a certain distance is formed between the first fixing portion 11 and the second fixing portion 21 along the radial direction of the terminal, so as to form a reserved space. The first antenna unit 10 and the second antenna unit 20 are not in contact with each other and are symmetrically arranged. Because the size of the terminal is designed to be smaller and the available space inside is also smaller, the design utilizes the space only on the surface of the terminal, increases the setting length of the antenna and can ensure the performance of receiving and transmitting signals.
More preferably, when the first fixing portion 11 and the second fixing portion 21 are disposed, they partially adhere to the end of the terminal in the axial direction thereof, that is, the top surface of the rectangular parallelepiped, and the other portion is disposed on the screen (TP surface) facing the metal cover body in the terminal, that is, the back surface of the TP surface. The terminal body facing to a plurality of directions is provided with the antennas, so that the range of the terminal capable of receiving signals can be enlarged.
The first extension 12 and the second extension 22 extend from the first fixing portion 11 and the second fixing portion 21 to the side of the terminal end, respectively, by a length of more than 15mm, more preferably 15-20mm, and most preferably 15mm. It will be appreciated that the portion without the extension on the side may be provided as a metallic material, while the portion facing the extension is of a plastics material, further increasing the metal ratio of the terminal housing.
With the configuration, the part of the rear cover of the terminal facing the rear cover is not provided with the antenna, so that the terminal with the antenna can be provided with the all-metal rear cover, and the side edge is partially metal, so that the performance of the antenna is not affected.
Further, when the antenna is applied to the inside of the smart terminal, the rear cover of the smart terminal is entirely made of metal. In the intelligent terminal, a control unit 30, such as a chip, a processor, etc., is electrically connected to the ground terminals of the first antenna unit 10 and the second antenna unit 20, and the control unit 30 has the function of switching which antenna to use. Specifically, the control unit 30 determines, according to the current signal frequency band information sent by the communication unit included in the intelligent terminal: the current environment of the smart terminal uses what frequency band to communicate with, if a low frequency signal is used in the current environment of the smart terminal, the control unit 30 switches to connect with the first antenna unit 10, and vice versa. The control unit 30 includes a single pole double throw switch (SP 2T) for switching the channel connected to the first antenna unit 10 or the second antenna unit 20. Other means such as selective connection of two channels are applicable.
In manufacturing the intelligent terminal with the all-metal cover body, the following steps can be adopted:
step one: when the intelligent terminal is not covered by the cover body, a first antenna unit and a second antenna unit are arranged at two corners of the end part of the intelligent terminal, so that the antennas are arranged in a sectional structure;
step two: the fixed first antenna unit and the second antenna unit extend along the side edge of the intelligent terminal to form an extension part, and the extension part is attached to the side edge of the intelligent terminal or the TP surface facing the metal cover body;
step three: the all-metal cover body is covered on the intelligent terminal to finish installation.
And the first antenna unit and the second antenna unit need to be configured in the same way, and the first frequency band and the second frequency band of the first antenna unit and the second antenna unit can cover the full frequency band after being overlapped.
It should be noted that the embodiments of the present invention are preferred and not limited in any way, and any person skilled in the art may make use of the above-disclosed technical content to change or modify the same into equivalent effective embodiments without departing from the technical scope of the present invention, and any modification or equivalent change and modification of the above-described embodiments according to the technical substance of the present invention still falls within the scope of the technical scope of the present invention.
