As shown in fig. 1, the main board 200 may include a plurality of feeds 210, and the plurality of feeds 210 are respectively connected to the plurality of antennas 100, that is, each antenna 100 may be connected to one feed 210. The feed source 210 is a primary radiator of the main and sub-reflecting surfaces of the excitation surface antenna, is an important device for determining the electrical characteristics and frequency bands of the antenna 100 connected with the feed source, and is used for radiating the radio frequency power from the feed line to the reflecting surface or lens in the form of electromagnetic waves, so that the radio frequency power generates proper field distribution on the caliber to form a required sharp beam or a shaped beam; meanwhile, the power leaked from the edge of the reflecting surface or the lens is minimized to realize the gain as high as possible. That is, the primary functions of the feed 210 are: electromagnetic wave signals received by the antenna 100 connected to the feed 210 are collected, converted into signal voltages, supplied to a tuner, and polarized.
It should be noted that the antenna 100 may include, but is not limited to, one or more of a GPS antenna, a WIFI antenna, a communication antenna, and the like. For example, the antenna 100 may be a GPS antenna, a WIFI antenna, or a communications antenna; for another example, the antenna 100 may also be a two-in-one antenna composed of a GPS antenna and a WIFI antenna; for example, the antenna 100 may be a two-in-one antenna composed of a GPS antenna and a communication antenna. In the embodiment of the present invention, the communication antenna may be a cellular mobile communication antenna, for example, the communication antenna may be a 2G/3G/4G antenna.
The metal battery cover 300 may include a plurality of first ground points 310. The position corresponding to the first grounding point 310 is used for grounding, so that the purpose of grounding is achieved when other components (such as a feed source and the like) of the mobile terminal are connected with the first grounding point 310.
The first connecting members 400 connect the first grounding points 310 to the second grounding points 220 of the main board 200, wherein the second grounding points 220 correspond to the feed sources 210. It should be noted that the plurality of second grounding points 220 correspond to the plurality of feeds 210, which means that the plurality of second grounding points 220 are close to the plurality of feeds 210, that is, each second grounding point 220 is close to one feed 210. Therefore, the lightning protection grounding measure of the antenna connected with the feed source can be ensured.
In conclusion, the metal battery cover can effectively solve the influence of the metal battery cover on the performance of the antenna by selecting a plurality of areas as grounding points and connecting the grounding points through the connecting piece.
It will be appreciated that the number of first ground points 310 may be many, such as two, four, eight, etc. As an example, the number of the first grounding points 310 may be four, and the four first grounding points 310 may be respectively located at four corner regions of the metal battery cover 300. In this example, when the first grounding point 310 is four, the number of the first connectors 400 connecting the first grounding point 310 and the second grounding point 220 may also be four. For example, as shown in fig. 1, a first grounding point 310 is disposed at each corner region of the metal battery cover 300, and first connecting members 400 connecting the first grounding point 310 and the second grounding point 220 are also disposed at four corner regions of the metal battery cover 300, respectively. Therefore, the positions of the four corner angle areas of the metal battery cover are selected as grounding points, and the grounding points are connected through the connecting piece, so that the influence of the metal battery cover on the performance of the antenna can be effectively solved.
In order to further reduce the influence of the metal battery cover on the performance of the antenna, as an example, as shown in fig. 2, the metal battery cover 300 may further include a plurality of third grounding points 320. Wherein, in this example, the antenna apparatus may further include: a plurality of second connectors 500, wherein the plurality of second connectors 500 can respectively connect the plurality of third grounding points 320 with the ground of the motherboard 200.

That is, a third grounding point 320 is disposed at the center of each side of the metal battery cover 300, and for each third grounding point 320, the third grounding point 320 can be connected to the ground of the main board 200 through a second connecting member 500.
Therefore, the first grounding point can be connected with the second connecting point of the mainboard through the first connecting piece, and the third grounding point can be connected with the ground of the mainboard through the second connecting piece, so that when the antenna 100 receives or sends signals, the current excited by the surface of the metal battery cover can quickly return to the ground of the mainboard through the first connecting piece and the second connecting piece, and a plurality of uncertain factors brought to the antenna performance by secondary radiation are effectively avoided.
In order to effectively avoid problems (such as static electricity) caused by the battery cover being charged due to a short circuit, as an example, as shown in fig. 3, the antenna device may further include: a plurality of first capacitors 600 and a plurality of second capacitors 700.

That is, a first capacitor 600 is disposed between each first connector 400 and the first ground point 310, and a second capacitor 700 is disposed between each second connector 500 and the third ground point 320. Therefore, a large capacitor is connected in series on the back earth path, the large capacitor is usually about 100PF, on one hand, the leakage can be prevented during charging, the possibility of electric shock caused by the fact that leakage current flows to the metal battery cover and a hand touches the battery cover is avoided, and on the other hand, the capacitor is equivalent to a short circuit for radio frequency signals and does not influence the grounding of the metal battery cover.
It is understood that the first connection member 400 and the second connection member 500 may be formed of various materials or structures having conductive characteristics. As an example, the first connector 400 and the second connector 500 may be spring plates, screws, pogo pin connectors, or the like. Therefore, the current excited by the metal battery cover can be quickly conducted to the ground of the mainboard by adopting the conductive characteristics of the elastic sheet, the screw or the spring pin type connector and the like, and a plurality of uncertain factors brought to the antenna performance by secondary radiation of the metal battery cover can be effectively avoided.
In order to effectively avoid the problem of conductive failure between the connection element and the ground point due to severe environments such as micro-drop and oxidation, in an embodiment of the present invention, the antenna apparatus may further include a first conductive cloth and a second conductive cloth, the first conductive cloth is located between the first ground point 310 and the first connection element 400, and the second conductive cloth is located between the third ground point 320 and the second connection element 500. In the embodiment of the present invention, the first conductive cloth and the second conductive cloth may be gold-plated conductive cloths, etc. Therefore, the problem of overlarge radio frequency impedance caused by poor contact in various severe environments can be effectively solved by adding the gold-plated conductive cloth at the contact part of the metal battery cover.
