Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
In the embodiments of the present invention, the mobile terminal may be implemented in various forms. For example, the terminal described in the present invention may include a mobile terminal such as a mobile phone, a smart phone, a notebook computer, a digital broadcast receiver, a Personal Digital Assistant (PDA), a tablet computer (PAD), a Portable Multimedia Player (PMP), a navigation device, etc., and a stationary terminal such as a digital TV, a desktop computer, etc. In the following, it is assumed that the terminal is a mobile terminal. However, it will be understood by those skilled in the art that the configuration according to the embodiment of the present invention can be applied to a fixed type terminal in addition to elements particularly used for moving purposes.
Example one
An embodiment of the present invention provides an antenna of a mobile terminal, and as shown in fig. 1, the antenna of the mobile terminal includes: the N-segment metal bezel 100 of the mobile terminal, the metal ground layer 200, the feeding circuit (not shown in fig. 1), and the frequency switching device 400.
The metal ground layer 200 is a rectangular plate-shaped structure, and is disposed in the mobile terminal housing to serve as a ground for the antenna. Optionally, the area of the metal stratum 200 is the same as that of the mobile terminal, and is arranged in the middle of the mobile terminal housing; here, the area of the metal ground layer 200 refers to the area of a rectangle, and the area of the mobile terminal may be the area of a screen.
Alternatively, the metal formation 200 is any metal material that can conduct electricity. For example, the metal formation 200 is a magnesium aluminum alloy material. The thickness of the metal formation 200 may be 0.4-0.6 mm, the thickness of the metal formation 200 may be set according to the specific structure of the mobile terminal, and when the space inside the mobile terminal is large, the thickness of the metal formation 200 is thick, for example, 0.6 mm; when the space inside the mobile terminal is small, the thickness of the metal ground layer 200 is thin, such as 0.4 mm.
At least one of the N metal frames 100 is connected to the feeding circuit through a feeding point 301, where the feeding point 301 may be disposed on at least one metal frame connected to the feeding circuit; the metal frame of the access feed circuit is used as a radiator of the antenna; the current in the feed circuit flows into the radiator through the feed point 301, and the current in the radiator generates electromagnetic waves; the radiator radiates electromagnetic waves to make the antenna transmit and receive signals. Wherein N is an integer of 1 or more.
The frequency switching device 400 is used to control the metal frames of different sections to access the feeding circuit, so that the antenna operates in different frequency bands.
The feeding circuit may be disposed on a main board of the mobile terminal, and other relevant contents related to the feeding circuit are not specifically described.
Further, referring to fig. 1 or fig. 2, the N-segment metal bezel 100 and the frequency switching device 400 are further described:
as for the N-segment metal frame 100, it can be known from the above that when different segments of metal frames are connected to the feeding circuit, the antenna operates in different frequency bands. Illustratively, when N is 5, the antenna includes 5 segments of metal frames, and as still shown in fig. 1 or fig. 2, the 5 segments of metal frames are a first side frame 101, a first corner frame 102, a bottom end frame 103, a second corner frame 104, and a second side frame 105, respectively; first side frame 101 sets up in the long one side of limit of mobile terminal, and second side frame 105 sets up in the long one side of limit of another of mobile terminal, and bottom frame 103 sets up in mobile terminal's bottom, and first turning frame 102 sets up between first side frame 101 and bottom frame 103, and second turning frame 104 sets up between second side frame 105 and bottom frame 103.
Illustratively, when only the bottom end frame 103 is connected to the feeding circuit, the antenna operates in a first frequency band, such as 990 mhz; when the bottom frame 103 and the first side frame 101 are simultaneously connected to the feeding circuit, the antenna operates in a second frequency band, such as 2.25 ghz.
In addition, when the antenna includes 5 sections of metal frames, the first side frame 101 and the second side frame 105 are used to lengthen the radiator of the antenna, so that the length of the radiator of the antenna can be lengthened or shortened, and the antenna can operate in more frequency bands to optimize the antenna.
In addition, each operating frequency band of the antenna may correspond to an antenna type, for example, when the antenna operates at 1575 mhz, the antenna type is a Global Positioning System (GPS) antenna; the antenna may be of the WIreless FIdelity (WIFI) variety when operating at 2.4 ghz.
Furthermore, gaps are formed between the N sections of metal frames, and the gaps can be filled with non-metal materials of the mobile phone shell. Alternatively, the size of the gap may be 0.5-2.0 mm. The size of the gap may also be determined according to an actual situation of the mobile terminal (for example, the size of the structure of the mobile terminal itself), which is not limited in this embodiment of the present invention.
Optionally, when the mobile terminal is a mobile phone, the feeding point 301 may be disposed on the bottom end frame 103, and at this time, the bottom end frame 103 is a main radiator of the antenna, that is, a radiator for a call.
In addition, when not all the side frames of the mobile terminal are used as the radiator of the antenna, the frame that is not used as the antenna radiator may be a metal frame or a non-metal frame. For example, in the frame of the mobile terminal shown in fig. 1, only the frames at the bottom ends of the two sides are radiators of the antenna, and the frame at the top end is not a radiator of the antenna; the top frame (three frames at the top) can be made of conductive metal material or non-metal material without conductive property.
Optionally, the N-segment metal frame 100 is a symmetrical structure. Illustratively, referring to fig. 1, the 5-segment metal bezel of fig. 1 is symmetrical about a line passing through the center of gravity of the mobile terminal and perpendicular to the bottom bezel 103.
Optionally, the N-segment metal frame 100 is made of an aluminum alloy material.
For the frequency switching device 400, optionally, the frequency switching device 400 is M single-pole multi-throw switches, where M is an integer greater than or equal to 1.
Illustratively, the antenna includes 2 single-pole 4-throw switches, i.e., M is 2, and the single-pole multi-throw switch is a single-pole 4-throw switch. The 2 single pole 4 throw switches are a first single pole 4 throw switch 401 and a second single pole 4 throw switch 402, respectively. In addition, the antenna further includes a first empty pin 106 and a second empty pin 107 (which may be blank in fig. 2, i.e., empty without any components connected).
Further, the two single-pole 4-throw switches adjust the working frequency band of the antenna by the following method: one end 401a of the first single-pole 4-throw switch 401 is connected to the bottom end frame 103 (as shown in fig. 2), and the other end 401b of the first single-pole 4-throw switch 401 is switched among the first side frame 101, the first corner frame 102, the metal layer 200, or the first dummy pin 106, so that the antenna operates in different frequency bands; for example, when the other end 401b of the first single-pole 4-throw switch 401 is connected to the metal ground layer 200, only the bottom end frame 103 is connected to the feed circuit, and the operating frequency of the antenna is 990 mhz at this time; when the other end 401b of the first single-pole 4-throw switch 401 is connected to the first side frame 101, the first side frame 101 is connected to the feeding circuit in addition to the bottom side frame 103, and the operating frequency of the antenna is 2.25 ghz. Similarly, one end 402a of the second single-pole 4-throw switch 402 is connected to the bottom end frame 103, and the other end 402b of the second single-pole 4-throw switch 402 is switched among the second side frame 105, the second corner frame 104, the metal ground layer 200, or the second dummy pin 107, so that the antenna can also operate in different frequency bands.
In addition, the positions of the first dummy pin 106 and the second dummy pin 107 are set as follows: arranging a first null pin 106 and a second null pin 107 near the M single-pole multi-throw switches, and ensuring that the other ends of the M single-pole multi-throw switches can be connected to the first null pin 106 and the second null pin 107; or, the other ends of the M single-pole multi-throw switches are directly thrown to be empty.
Further, since the frequency switching device 400 includes 2 single-pole 4-throw switches, each of which can have four different connection methods, there are 16 different connection methods. For convenience of description, the connection positions of the other end 401b of the first single-pole 4-throw switch 401 to the metal frames (the first side frame 101, the first corner frame 102, the metal ground layer 200, and the first dummy pin 106) are sequentially denoted as a1, a2, a3, and a 4; the positions of the connection of the other end 402b of the second single-pole 4-throw switch 402 to the metal frames (the second side frame 105, the second corner frame 104, the metal ground layer 200, and the second dummy pin 107) are sequentially denoted as b1, b2, b3, and b4, respectively. Then 16 different connections include: (a1, b1), (a1, b2), (a1, b3), (a1, b4), (a2, b1), (a2, b2), (a2, b3), (a2, b4), (a3, b1), (a3, b2), (a3, b3), (a3, b4), (a4, b1), (a4, b2), (a4, b3), (a4, b 4).
As can be seen from the above, when the value of N is larger, that is, the antenna includes a plurality of metal frames, the metal frames are connected to the single-pole multi-throw switch in a plurality of ways; when the value of N is small, the antenna includes a small number of metal frames, and the metal frames are connected to the single-pole multi-throw switch in a small manner. Therefore, the value of N can be set according to the actual situation of the number of the working frequency bands of the antenna required by the mobile terminal, and when the working frequency bands of the antenna required by the mobile terminal are more, the value of N is larger; when the working frequency band of the antenna required by the mobile terminal is less, the value of N is smaller so as to ensure that the frequency band included by the antenna meets the use requirement of the mobile terminal.
It should be noted that when the first single-pole 4-throw switch 401 or the second single-pole 4-throw switch 402 is connected to the metal ground layer 200, the Antenna includes a feeding point and at least one grounding point, i.e., when the Antenna is a Planar Inverted-F Antenna (PIFA). When neither end of the first single-pole 4-throw switch 401 or the second single-pole 4-throw switch 402 is connected to the metal ground 200, the Antenna only includes a feeding point and does not include a grounding point, i.e., the Antenna is a Monopole Antenna (Monopole Antenna), and the working principle of the planar inverted-F Antenna and the Monopole Antenna is not described herein in detail for the prior art.
Optionally, still referring to fig. 1 or fig. 2, when M is an even number, the M single-pole multi-throw switches are disposed at symmetrical positions of the mobile terminal. For example, in fig. 1 and 2, the antenna includes two single-pole multi-throw switches that pass through the center of gravity of the mobile terminal and are symmetrical to each other in a straight line perpendicular to the bottom end frame 103
It should be noted that the frequency switching device 400 can also be another number of single-pole multi-throw switches, which can be set to 1 to 4, and in practical applications, it is generally set to 1 or 2. When the frequency switch 400 includes more single-pole multi-throw switches, the frequency switch 400 can adjust the connection between more metal frames and the frequency switch 400, so that the antenna includes more radiators with different numbers and different shapes, where the different shapes mainly refer to different lengths of the radiators of the antenna, and thus the antenna includes more working frequency bands; when the frequency switch 400 includes a small number of single-pole multi-throw switches, the frequency switch 400 can adjust the connection between the small number of metal frames and the frequency switch 400, so that the number of radiators with different numbers and shapes included in the antenna is small, and the working frequency band of the antenna is small. Therefore, the number of the single-pole multi-throw switches included in the frequency switching device 400 is determined by the actual condition of the antenna required by the mobile terminal, and when the mobile terminal requires an antenna with a larger operating frequency band, the frequency switching device 400 includes a larger number of single-pole multi-throw switches; when the mobile terminal requires an antenna with less operating frequency band, the frequency switching device 400 includes a smaller number of single-pole multi-throw switches. Illustratively, when the mobile terminal requires 10 antennas for operating frequency bands, the frequency switching device 400 includes three single-pole multi-throw switches; when the mobile terminal needs four antennas in the operating frequency bands, the corresponding frequency switching device 400 includes a single-pole multi-throw switch.
It should also be noted that the frequency switching device 400 can also be M multi-pole multi-throw switches. For example, the frequency switching device 400 can also be a double-pole double-throw switch. Alternatively, the double pole double throw switch is installed at a position where the first single pole 4 throw switch 401 is installed, but the double pole double throw switch may be installed at a position where the second single pole 4 throw switch 402 is installed. In this case, the double pole double throw switch includes three connection terminals, namely a first connection terminal, a second connection terminal (the first end with the throw pole) and a third connection terminal (the second end with the throw pole).
Illustratively, still taking the example shown in fig. 1 or fig. 2 as an example, in this case, the first connection end of the double-pole double-throw switch is connected to the bottom frame 103, the second connection end is connected to the metal ground layer 200, and the third connection end is connected to the first side frame 101 to form the planar inverted-F antenna. Of course, a monopole antenna can also be formed, and the connection method is as follows: the first connection end is still connected to the bottom frame 103, the second connection end is connected to the first side frame 101, and the third connection end is connected to the first empty pin 106. Of course, when the frequency switching device 400 is a double-pole double-throw switch, there are other connection methods, which are not described in detail herein.
In addition, referring to fig. 3A to 3E, the embodiment of the present invention further provides return loss graphs corresponding to 5 connection modes when N is 5 and the frequency switching device 400 is two single-pole 4-throw switches. The 5 connection modes are (a3, b3), (a1, b3), (a3, b1), (a2, b2) and (a2, b1), respectively. As shown in fig. 3A, when the connection mode is (a3, b3), the operating frequencies of the antenna include 850 mhz, 1.85 ghz, and 2.25 ghz; as shown in fig. 3B, when the connection mode is (a1, B3), the operating frequency of the antenna is 2.1 ghz; as shown in fig. 3C, when the connection mode is (a3, b1), the operating frequency of the antenna is 2.42 ghz; as shown in fig. 3D, when the connection mode is (a2, b2), the operating frequency of the antenna is 990 mhz; as shown in fig. 3E, when the connection is (a2, b1), the operating frequency of the antenna is 2.65 ghz.
In addition, it should be noted that other metal frames of the mobile terminal may also be used as a part of the antenna radiator, and different antennas may be designed by combining with other structures. For example, the bottom side frame and the top side frame of the mobile terminal may be used as a part of an antenna radiator, and the rear case of the mobile terminal may be wired to contact the bottom side frame and the top side frame by a Laser Direct Structuring (LDS) technique, and may also be used as an antenna radiator to design a desired antenna. Other different antennas may be designed, and are not described in detail herein.
In summary, in the antenna of the mobile terminal provided in the embodiments of the present invention, the radiator of the antenna is a multi-section metal frame of the mobile terminal, and the radiator is not disposed inside the mobile terminal, so that the signal transmission and reception of the antenna is no longer influenced by shielding and other effects of the housing of the mobile terminal, and the signal transmission and reception capability of the antenna is further improved; and when the radiator of the antenna is a multi-section metal frame of the mobile terminal, the space is saved in the shell of the mobile terminal, so that the design of other structures of the mobile terminal is more convenient. In addition, when the working frequency of the antenna is adjusted, the antenna of the mobile terminal provided by the embodiment of the invention is adjusted through the M single-pole multi-throw switches without other circuit settings, so that the setting of circuits in the mobile terminal is reduced, the space in the shell of the mobile terminal is saved, and the design of other structures of the mobile terminal is more convenient; and the working frequency of the antenna can be adjusted only by M single-pole multi-throw switches, so that the operation process of adjusting the frequency band is convenient.

It should be noted that, for all antenna contents related in the embodiment of the mobile terminal, reference may be made to the detailed description in the first method embodiment, which is not described herein again.
In summary, in the antenna of the mobile terminal provided in the embodiments of the present invention, the radiator of the antenna is a multi-section metal frame of the mobile terminal, and the radiator is not disposed inside the mobile terminal, so that the signal transmission and reception of the antenna is no longer influenced by shielding and other effects of the housing of the mobile terminal, and the signal transmission and reception capability of the antenna is further improved; and when the radiator of the antenna is a multi-section metal frame of the mobile terminal, the space is saved in the shell of the mobile terminal, so that the design of other structures of the mobile terminal is more convenient.
