As shown in fig. 1, the antenna according to the embodiment of the present invention includes a main metal frame 11, a first corner metal frame 12, and a second corner metal frame 13. The main metal frame 11, the first corner metal frame 12, and the second corner metal frame 13 are all made of metal.
As shown in fig. 1, two ends of the main metal frame 11 in the length direction are a first end 11a and a second end 11b, and a first corner metal frame 12 and a second corner metal frame 13 are respectively disposed on two sides of the main metal frame 11 in the length direction, wherein the first corner metal frame 12 is disposed on one side (for example, the left side shown in fig. 1) adjacent to the first end 11a in the length direction of the main metal frame 11, and the second corner metal frame 13 is disposed on one side (for example, the right side shown in fig. 1) adjacent to the second end 11b in the length direction of the main metal frame 11.
For example, in the example of fig. 1, the main metal frame 11 extends along a straight line in the horizontal direction, the left end of the main metal frame 11 is a first end 11a, the right end of the main metal frame 11 is a second end 11b, and the first corner metal frame 12 and the second corner metal frame 13 are both substantially formed in an "L" shape and are respectively disposed on the left and right sides of the main metal frame 11, wherein the first corner metal frame 12 is disposed on the left side of the main metal frame 11, and the second corner metal frame 13 is disposed on the right side of the main metal frame 11.
Referring to fig. 1, the main metal frame 11 is an antenna main radiator, the first end 11a is connected to the motherboard 4 through the feeding end 3, the one end 12a of the first corner metal frame 12 extends toward the first end 11a and defines a first gap 21 with the first end 11a, the other end 12b of the first corner metal frame 12 is connected to the motherboard 4, and thus, the first corner metal frame 12 may be a parasitic antenna, the one end 13a of the second corner metal frame 13 extends toward the second end 11b and defines a second gap 22 with the second end 11b, and a third gap 23 is defined between the other end 13b of the second corner metal frame 13 and the motherboard 4.
Here, it should be noted that, in the description herein, the "slit" refers to: the parts on both sides of the gap are completely disconnected, and the 'gap' refers to that: so that the parts on both sides of the slot are not completely disconnected and still connected.
According to the antenna for the terminal provided by the embodiment of the invention, the second corner metal frame 13 is arranged, and the second corner metal frame 13 and the first corner metal frame 12 can be arranged in an axial symmetry manner, so that the whole structure of the antenna is attractive in appearance, and the third gap 23 is formed between the second corner metal frame 13 and the main board 4 and is not connected, so that the third gap 23 can effectively improve the adverse effect of the second corner metal frame 13 on the main metal frame 11, and the efficiency of the main metal frame 11 is improved.
In one embodiment of the present invention, the second corner metal frame 13 and the first corner metal frame 12 are symmetrically arranged with respect to a center line in a length direction of the main metal frame 11. Therefore, the whole antenna is attractive in appearance and atmosphere. For example, in the example of fig. 2, the main metal frame 11 extends along a straight line in the left-right direction, the first corner metal frame 12 extends horizontally from right to left and then extends in the vertical direction, and the second corner metal frame 13 extends horizontally from left to right and then extends in the vertical direction, so as to be symmetrical to the structure of the first corner metal frame 12. Here, it should be noted that the symmetrical arrangement is to be understood in a broad sense, and when the structures of the first corner metal frame 12 and the second corner metal frame 13 are substantially symmetrical and slightly different in detail, the first corner metal frame 12 and the second corner metal frame 13 are to be understood as being symmetrically arranged.
Referring to fig. 3, a first slit 24 that prevents the first corner metal frame 12 from being broken is formed in the first corner metal frame 12, that is, the first slit 24 is formed as a groove opened in the first corner metal frame 12, and only the groove is opened instead of a gap, so that the first corner metal frame 12 is ensured to be continuous and complete without being opened into a multi-segment and multi-segment structure, so as to ensure that the performance of the first corner metal frame 12 is good, wherein the opening positions of the first slit 24 and the opening positions of the third slit 23 are symmetrically arranged about a center line in the length direction of the main metal frame 11. Therefore, the first slot 24 configured as a pseudo slot is opened in the first corner metal frame 12, so that the overall structure of the antenna is symmetrical and beautiful.
Further, at least one fourth slit for breaking the second corner metal frame 13 is further formed on the second corner metal frame 13, that is, a plurality of fourth slits configured as real slits are formed on the second corner metal frame 13, so that the second corner metal frame 13 can be broken into a plurality of sections and a plurality of sections, and thus, the adverse effect of the second metal frame on the main metal frame 11 can be further improved.
Of course, preferably, when the second corner metal frame 13 is formed with a plurality of fourth slits, a plurality of dummy slits may be correspondingly formed at symmetrical positions on the first corner metal frame 12, so as to ensure that the structure of the first corner metal frame 12 is symmetrical to that of the second corner metal frame 13, and the appearance is beautiful.
In an embodiment of the present invention, a switch for controlling the connection and disconnection between the other end 13b of the second corner metal frame 13 and the main board 4 is disposed in the third slot 23, and the connection and disconnection of the third slot 23 may change the frequency offset of the main metal frame 11, so that the efficiency of the main metal frame 11 may be optimized by controlling the connection and disconnection of the switch.
For example, in the example of fig. 4, a frequency-efficiency curve of the main metal frame 11 is shown, wherein the abscissa represents the frequency f, the ordinate represents the efficiency η, the curve a1 represents the frequency-efficiency curve of the main metal frame 11 when the third slot 23 is connected and the second corner metal frame 13 is connected to the main board 4, the curve a2 represents the frequency-efficiency curve of the main metal frame 11 when the second slot 22 is disconnected and the second corner metal frame 13 is not connected to the main board 4, as is apparent from the figure, when the frequency is less than 775MHz, the third slot 23 is controlled to be blocked (i.e. the second corner metal frame 13 is not connected to the main board 4), when the frequency is less than 845MHz and greater than 775MHz, the third slot 23 is controlled to be connected (i.e. the second corner metal frame 13 is connected to the main board 4), when the frequency is greater than 845MHz, the third slot 23 is controlled to be blocked (i.e. the second corner metal frame 13 is not connected to the main, therefore, the efficiency of the main metal frame 11 can be effectively improved, and the low-frequency performance of the main metal frame 11 is improved.
Preferably, when the switch is disposed in the third gap 23, a fourth gap for disconnecting the second corner metal frame 13 is preferably not processed on the second corner metal frame 13, otherwise, the function and function of the switch will be affected, but at least one second slot for disconnecting the second corner metal frame 13 may be processed on the second corner metal frame 13, that is, a plurality of second slots configured as dummy gaps may be processed on the second corner metal frame 13, so that the structure of the second corner metal frame 13 may be more beautiful.
