TECHNICAL FIELD

[0001] The present application relates to the technical field of antennas, in particular to an antenna and a base station. BACKGROUND

[0002] With the rapid development of mobile communication technology, more stringent technical requirements are put forward for the overall communication system architecture. The communication system requires not only efficient, fast and large-capacity communication, but also high integration, miniaturization and light weight. Electrically adjustable antenna is the mainstream of antenna in today's communication system, and phase shifter is an important component of electrically adjustable antenna. The existing phase shifter, power divider and radiation element are connected through cable or adapter probe. The integration of each component in this structure is not high, which is not conducive to the miniaturization and light weight of the antenna. Moreover, the existing phase shifter has low integration, many parts and complex structure, and the production process is also more. SUMMARY

[0003] The present application provides an antenna with fewer components and convenient installation.

[0004] In a first aspect, an embodiment of the present application provides an antenna, comprising a reflecting plate, a feed network plate and a sliding medium part. The reflecting plate comprises a receiving part arranged towards the feed network plate. The feed network plate is arranged on one side of the reflecting plate and comprises a first conductor. The first conductor and the sliding medium part are located in the receiving part, and the sliding medium part is located between the first conductor and the receiving part. The receiving part has a first opening. The first conductor, the sliding medium part, the first opening and the receiving part extend in the same direction. The feed network plate can be a PCB plate or other metal plate.

[0005] The first conductor, the sliding medium part, the first opening and the receiving part extend in the same direction, which means that the extension direction of the first conductor, the sliding medium part, the first opening and the receiving part as a whole is the same. In this embodiment, the receiving part as a whole extends along a first direction, and the first conductor, the sliding medium part and the first opening extend along the first direction. The first direction is the length direction of the reflecting plate and is a straight line. In some embodiments, the extension direction of the receiving part can also be a curve.

[0006] In the present application, the receiving part has a receiving space, the receiving space is in communication with the first opening, the first conductor and the sliding medium part are located in the receiving space, and the first conductor is spaced apart from the receiving part by the sliding medium part, so that the first conductor and the receiving part are electrically isolated and are not electrically connected. In the present application, the sliding medium part can be completely located in the receiving space of the receiving part, and the sliding medium part can also extend out of the receiving space from the first opening and only partially located in the receiving space.

[0007] In the application, the reflector is also used as the radio frequency ground of the phase shifter, and the reflector includes a reflector body and a receiving portion. The receiving portion is a part of the reflector, that is, the receiving portion is also the radio frequency ground. The components of the phase shifter include a first conductor, a sliding medium portion, and the reflector (including the receiving portion). In the phase shifter, the first conductor serves as an inner conductor, the reflector serves as an outer conductor, that is, the radio frequency ground, the radio frequency ground is the reference ground of the signal in the first conductor, and the sliding medium portion is located between the first conductor (the inner conductor) and the reflector (the outer conductor). The relative position with the first conductor is changed by moving the sliding medium portion, and then the dielectric constant between the first conductor and the reflector is changed, so that the phase of the signal in the first conductor is changed, so that the vertical plane beam of the antenna forms a specific downtilt angle. The feed network board can drive the sliding medium portion to move to realize different radiation beam pointing through the transmission component. The phase to be changed of the signal in the first conductor can set the sliding position of the sliding medium portion or the dielectric constant of the sliding medium portion itself according to actual needs. In the application, no additional components are needed as the radio frequency ground. The reflector as a whole serves as the radio frequency ground by setting the receiving portion, which can reduce the number of parts, save design space, and make the structure of the antenna simpler.

[0008] In the application, the first conductor can be conveniently placed in the receiving portion by setting the first opening on the receiving portion, the first opening being the same as the extension direction of the receiving portion. When the feed network board is located on the reflector, the structure of the part near the first conductor in the feed network board is adapted to the structure of the receiving portion and the first opening, so that the first conductor can be conveniently placed in the receiving portion.

[0009] In the application, the reflector serves as the radio frequency ground of the phase shifter by setting the receiving portion, no additional components are needed as the radio frequency ground, which can reduce the number of parts, save design space, and make the structure of the antenna simpler. On the other hand, the first conductor can be conveniently placed in the receiving portion by setting the first opening on the receiving portion, which makes the preparation process of the antenna simpler.

[0010] In the application, the first conductor can be a signal line in the feed network board that needs to change the phase of the signal.

[0025] In a possible implementation, the cross section of the accommodation portion is arc-shaped. The arc-shaped cross section includes a circular arc shape or an elliptical arc shape. When the cross section of the accommodation portion is circular arc-shaped, the curvature of the circular arc can be set according to actual needs.
