It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1, fig. 1 is a schematic view of a metal back cover according to the present invention. The embodiment provides an all-metal four-in-one antenna, and the embodiment only takes a tablet computer as an example for illustration.
The all-metal four-in-one antenna comprises a metal frame 10 and a plastic back cover 20 fixedly arranged in the metal frame 10.
In this example, a physical simulation was performed, in which a double-layer via PCB was used for the PCB board 30, the whole machine was 256mm x 175mm x 8.5mm (including the thickness of the back cover and the metal frame), and the substrate was FR4 (epsilon=4.3δ=0.024).
A PCB 30 is fixedly mounted on the plastic back cover 20, a certain distance is formed between the PCB 30 and the metal frame 10, and only one position of the PCB 30 is provided with a protruding portion 31 abutting against the metal frame 10.
A first breakpoint 11 and a second breakpoint 12 are arranged on one side of the metal frame 10, and the side is divided into three sections by the first breakpoint 11 and the second breakpoint 12; the other opposite side of the metal frame 10 is provided with a third break point 13 and a fourth break point 14, which side is divided into three sections by the third break point 13 and the fourth break point 14.
As shown in fig. 2 and 3, fig. 2 is a schematic diagram of an antenna model of the present invention; fig. 3 is a schematic diagram of a second antenna module according to the present invention.
A first long branch 15, a second long branch 17, a short branch 33, a second connecting branch 18 and a third connecting branch 19 are sequentially arranged between the first breakpoint position 11 and the second breakpoint position 12. The first long branch 15, the second long branch 17, the short branch 33, the second connecting branch 18 and the third connecting branch 19 are L-shaped, the first long branch 15 and the second long branch 17 are parallel to the PCB board 30, one ends of the two are respectively connected to the metal frame 10, and the other ends are connected together and are connected to the feeding point 32 on the PCB board 30 through a first connecting branch 16.
And a containing area is formed between the first long branch 15, the second long branch 17 and the first connecting branch 16, the metal frame 10 and the PCB 30 after being connected.
The short branch 33 is L-shaped, one end of which is connected with the PCB board 30, and the other end of which is not in contact with the metal frame 10, and forms a gap with the metal frame 10.
The second connecting branch 18 and the third connecting branch 19 are L-shaped, one end of each of which is connected with the metal frame 10, and the other end is connected with the PCB board 30.
Likewise, the same fixing areas as the above-mentioned receiving areas may be formed between the short stub 33, the second connection stub 18, and the third connection stub 19 and the metal bezel 10 and the PCB 30 for fixedly mounting the antenna mount 40 (see fig. 3).
