Because the matching circuit is connected with the antenna, the value of the electrical element connected with the antenna can be changed by adjusting the value of each electrical element in the matching circuit, thereby playing a role in adjusting the working frequency band of each antenna. As shown in fig. 2, the first matching circuit 200 includes:

the first inductor 201 includes a first terminal 1 and a second terminal 2. The first end 1 is electrically connected with the first feed point 103, and the second end 2 is grounded GND;

As shown in fig. 1, the second metal housing 108 is butted against one side of the first metal housing 101. For better butt joint effect, the first metal housing 101 and the second metal housing 108 have the same configuration. A gap 106 is formed between the first metal housing 101 and the second metal housing 108, and the gap 106 is filled with the above-mentioned filling bar (not shown). The filling strip may be made of insulating materials such as plastic, plastics, etc., and those skilled in the art may select a corresponding insulating material according to a specific use scenario, which is not limited in the disclosure.

The following describes an application of an antenna module in a smart phone with a specific embodiment.

In an embodiment of the present disclosure, the antenna module is applied to a smart phone, wherein the first metal housing 101 and the second metal housing 108 may serve as a metal rear case (e.g., a segmented metal rear case) of the smart phone. Wherein the first metal housing 101 may be arranged on top of the smartphone. In order to fix the display panel, in an embodiment of the present disclosure, a first supporting portion 109 is further disposed on the first side 105, and a second supporting portion 109 'is disposed on a side opposite to the first side, and is folded along the first folding line 110, the second folding line 110', and the third folding line 111, respectively. Referring to fig. 3, in the plane direct coordinate xoy, the first folding line 110 and the second folding line 110' are parallel to the x-axis, and the third folding line 111 is parallel to the y-axis, respectively. From the left side to the right side of fig. 3, the first support portion 110 rotates clockwise about the first folding line 110 to form a first frame, and the second support portion 110 'rotates counterclockwise about the second folding line 110' to form a second frame; when viewed from the lower side to the upper side of fig. 3, the metal portion of the left portion of the third folding line 111 is rotated counterclockwise around the third folding line to form the top frame 112, and the remaining portion forms the first back panel 113. After being folded, as shown in fig. 4, the first metal housing 101 forms a first space structure with an opening on one side, the first space structure is formed by sequentially connecting a first frame 109 (corresponding to the first supporting portion 109, only the position of which is changed, and therefore the same number is used), a top frame 112, and a second frame 109 '(corresponding to the second supporting portion 109'), and then is formed with the first back plate 113, and the opening of the first space structure is located on the side of the gap 106, that is, the opening of the first space structure is located on the right in fig. 4. Likewise, the second metal shell 108 may be provided with a support plate 109 "and the same folding process as the first support plate 109 is performed. Another support plate (not shown) is disposed on the opposite side of the support plate 109 ", so that the second metal shell 108 can also form a second space structure with an open side after being folded. The opening of the second spatial structure is located on the side of the slit 106, i.e. the opening of the second spatial structure is to the left in fig. 4. The open side of the first spatial structure matches the open side of the second spatial structure in shape, and the resulting gap 106 is filled with a filler strip (not shown in the figure).

In practical application, the metal shell formed by the first space structure and the second space structure is used for placing a display screen of the smart phone. As shown in fig. 5, the display screen 30 includes a display portion 302 and an extension portion 301. The extension 301 is disposed between the display portion 302 and the top frame of the first metal housing 101, and the extension 301 and the first back plate 113 of the first metal housing 101 have a first accommodating space (not shown in the figure).

As shown in fig. 6, a rear camera 114 is provided in the first accommodation space. The rear camera 114 extends into the first accommodating space through a first preset opening 115 on the first back plate 113. And the first connecting rib 102 is disposed right above the rear camera 114, i.e. a central connecting line (not shown) of the first predetermined opening 115 and the first connecting rib 102 is parallel to the first frame 109 of the first metal shell.

In an embodiment of the present disclosure, the first connection rib 102, the first feed point 103, and the first metal housing 101 form a first IFA antenna. In an embodiment of the present disclosure, the first IFA antenna may generate a GPS rf signal of 1525MHz to 1575 MHz. That is, the radiation range of the rf signal of the first IFA antenna is concentrated in the lower left corner region of the smartphone (the spatial region formed by the curve 116 with the top frame and the first bezel, in particular, the rf signal is concentrated at the gap in this region).

It can be seen that the first IFA antenna is arranged in the above corner region, and the distance from the palm of the user is the largest (the user holding position is usually located in the middle lower part of the smartphone), so as to reduce the interference of the user on the radio frequency signal of the antenna. In addition, the first connecting rib 102 is disposed right above the rear camera 114 and connected to the second metal housing 108 (equivalent to being grounded), and the rear camera is also grounded, that is, the influence on the first IFA antenna is reduced when the rear camera is turned on. Furthermore, since the first connecting rib 102 and the rear camera are grounded simultaneously, the difference of the receiving performance of the first IFA antenna is small when the rear camera is turned on or off, that is, the sense performance of the first IFA antenna is improved.

In an embodiment of the present disclosure, the smart phone further includes a first matching circuit. The first matching circuit is fixed at a first preset position in the first accommodating space. The first predetermined position is disposed around a feed point of the first IFA antenna (not shown).

In an embodiment of the present disclosure, as shown in fig. 7, the smart phone further includes a receiver 117 and a front camera 118. As shown in fig. 5, the receiver 117 and the front camera are arranged in one way. The receiver 117 extends into the first accommodating space through a second predetermined opening on the display screen extension 301. As shown in fig. 7, a second IFA antenna 119 is provided between the receiver 117 and the front camera 118. The feed point 120 of the second IFA antenna 119 is located in the first receiving space and the ground point 121 of the second IFA antenna 119 is located beside the feed point 120. It can be seen that the front camera 118 extends into the first accommodating space through a third preset opening on the extension 301. The first back plate 113, the first connecting rib 102, the second connecting rib 107, the receiver 117 and the front camera 118 constitute a second reflective back plate 116'. The second reflective backplane may reflect the rf signal in the second frequency band of the second IFA antenna 119 toward the display screen. The second frequency band may be set to 2400MHz to 2500MHz and 5150MHz to 5850MHz WIFI signals.

In the embodiment of the present disclosure, by providing the first connecting rib 102 and the second connecting rib 107, the formed second reflection back plate can reflect the radio frequency signal of the second IFA antenna, so that the radio frequency signal is more concentrated on the display screen side, and the radio frequency performance of the second IFA antenna is improved.

In an embodiment of the present disclosure, the smart phone further includes a second matching circuit and a second test socket. The second matching circuit is connected in series between the feed point 120 of the second IFA antenna and the second test socket. In an embodiment, referring to fig. 2, the second matching circuit is implemented by using the same circuit as the first matching circuit, and is not described herein again. The second matching circuit is fixed at a second preset position in the first accommodating space. The second predetermined position is disposed around a feed point of the second IFA antenna.

To this end, as shown in fig. 7, in an embodiment of the present disclosure, the first connecting rib 102 and the second connecting rib 107 make the radio frequency signal radiation area of the first IFA antenna concentrate on the lower left corner of the smart phone, and the radio frequency signal of the second antenna concentrates on the side of the display screen, so that the isolation between the first IFA antenna and the second IFA antenna is improved, and the mutual influence between the two IFA antennas is reduced.
