When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a block diagram illustrating an antenna disposed on a terminal according to an exemplary embodiment. As shown in fig. 1, the antenna includes:

a feed point 101 for outputting a radiation signal; the feed point 101 is arranged on the top frame 102;

the top frame is a part of a frame of the terminal, and an antenna and a camera are generally arranged at the top frame.

A metal back cover 103 for receiving and reflecting the radiation signal;

the metal rear cover 103 has an inner surface and an outer surface, the outer surface is a surface which is usually held by hand, and the inner surface is a surface which faces the top frame 102. The reflector plate, which receives and emits the radiation signal, is the inner surface. The metal rear cover 103 is a rear cover of the terminal.

The rib position 104 is used for blocking the radiation signals and other radiation signals, the rib position connects the top frame with the injection molding strip 1031 on the metal rear cover 103, and the rib position 104 is also used for receiving and reflecting the radiation signals.

The injection molding strip 1031 is disposed on the metal rear cover 103 at a position corresponding to a gap between the top frame and the middle frame.

The other radiated signals may be signals radiated out by feed points of other antennas on the terminal. The rib position of this embodiment is equivalent to a wall, and the radiation signal is kept apart with other radiation signals, but rib position 104 can't keep apart radiation signal and other radiation signals completely, only can keep apart most.

Since fig. 1 is a plan view from the outer surface of the metal back case to the inside of the terminal, it is equivalent to the metal back case being transparent. The rib 104 is solid, and connects the top frame 102 and the metal rear cover 103 as shown in fig. 2 and 3 (side view). The rib position 104 in fig. 2 and 3 is slightly different, but both can achieve the effect of isolating the signal.

In one embodiment, as shown in fig. 4, the antenna further includes:

a radiation area 105 for reflecting a radiation signal to the surroundings; the radiation zone 105 is arranged on the top frame below the feed point 101. The radiating area 105 allows fine tuning of the resonance position of the antenna.

The radiation area 105 receives the radiation signal emitted by the feed point 101 and reflects it out. The radiation zone 105 is placed at the bottom of the feed point 101.

In one embodiment, as shown in fig. 4, rib 104 is a metal plate 1041, and the width of metal plate 1041 is set according to the antenna pattern of the antenna.

In one embodiment, the rib 104 is at least two metal rods 1042 connecting the top frame and the terminal, and the total width of the at least two metal rods 1042 is set according to the antenna pattern of the antenna. As shown in fig. 5, the present embodiment is described by taking two metal rods 1042 as an example.

In one embodiment, as shown in fig. 6, the antenna further comprises:

a back surface of camera 106 for reflecting a radiation signal radiated by the radiation area;

the back surface of the camera head 106 is metallic and therefore can act as a reflector plate.

A back surface of the handset 107 for reflecting the radiated signal at least once.

The back surface of the earpiece 107 is also metallic and therefore acts as a reflector as well.

In one embodiment, the tendon positions 104, the camera 106, and the earpiece 107 are at least 5mm from the feed point 101.

In one embodiment, as shown in fig. 7, the antenna further comprises:

an antenna circuit 108 for receiving the signal and generating a radiated signal from the signal, the output of the antenna circuit 108 being the feed point 101.

The pattern of antenna circuitry 108 is disposed in the space between the top frame and the screen.

The signal may be a request signal generated by the terminal or an instruction signal issued.

The WiFi antenna in this embodiment may be a WiFi 5G antenna.

In this embodiment, the rib position 104 and the metal rear cover 103 on both sides of the feed point 101, the earpiece 107 and the camera 106 can be used as a reflection back plate, so that the monopole antenna radiates to the screen side more intensively, thereby greatly improving the WiFi performance.

any one of the above antennas, the antenna comprising:
