Abstract

The disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a data transmission rate higher than 4th generation (4G) communication systems such as long term evolution (LTE). A radio frequency (RF) filter in a wireless communication system is provided. The RF filter includes a structure including a resonance unit, and a cover plate at which a tuning structure is formed. The tuning structure includes a flexible arrangement with respect to the cover plate through an opening in the cover plate.

First claim

What is claimed is:

1 . A radio frequency (RF) filter in a wireless communication system, the RF filter comprising:
a structure comprising a resonance portion; and a cover plate at which a tuning structure is formed, wherein the tuning structure comprises a flexible arrangement with respect to the cover plate through an opening in the cover plate.

2 . The RF filter of claim 1 ,
wherein the tuning structure is formed by at least a portion of a member corresponding to the opening in the cover plate, and wherein the member comprises at least one region connected to the cover plate.

3 . The RF filter of claim 1 , wherein the tuning structure is integrally formed with the cover plate.

4 . The RF filter of claim 1 ,
wherein the cover plate comprises a metal plate, and wherein the tuning structure comprises at least a portion of the metal plate corresponding to the opening.

5 . The RF filter of claim 1 ,
wherein the flexible arrangement comprises one of a plurality of arrangements with respect to the cover plate, and wherein the plurality of arrangements correspond to distances between different tuning structures and a resonator of the resonance portion, respectively.

6 . The RF filter of claim 1 ,
wherein the tuning structure is disposed in at least a partial region of the opening in the cover plate, and wherein the tuning structure comprises an arrangement that is movable in an up direction and a down direction with respect to the cover plate.

7 . The RF filter of claim 1 , wherein the structure comprises one or more metal cavities and a resonator disposed in each of the one or more metal cavities.

8 . The RF filter of claim 1 ,
wherein the structure comprises a resonance substrate in which one or more resonators are formed as a single layer, and wherein the resonance substrate is disposed between the cover plate and a filter board.

9 . The RF filter of claim 1 , wherein the tuning structure on the cover plate is disposed in a region corresponding to a position of a resonator of the resonance portion on a filter board.

10 . The RF filter of claim 1 ,
wherein the tuning structure is connected to the cover plate through a fixator, and wherein the tuning structure comprises a movable arrangement with respect to the fixator.

11 . The RF filter of claim 10 ,
wherein the tuning structure comprises structures having a see-saw structure comprising a first end and a second end, and wherein the first end of the see-saw structure of the tuning structure is arranged to be symmetrical with the second end of the see-saw structure of the tuning structure with respect to the fixator.

12 . The RF filter of claim 1 , wherein a resonance frequency of the RF filter depends on a distance between the tuning structure and a resonator of the resonance portion.

13 . The RF filter of claim 1 ,
wherein the tuning structure corresponds to one region of the cover plate, and wherein the one region is flexibly disposed such that a distance to a resonator of the resonance portion is variable.

14 . A massive multiple-input multiple-output (MIMO) unit (MMU) device in a wireless communication system, the MMU device comprising:
at least one processor; a plurality of radio frequency (RF) filters; and an antenna array configured to radiate a signal, wherein an RF filer among the plurality of RF filters comprises a structure comprising a resonance portion and a cover plate at which a tuning structure is formed, and wherein the tuning structure comprises a flexible arrangement with respect to the cover plate through an opening of the cover plate.

15 . The MMU device of claim 14 ,
wherein the cover plate comprises a metal plate, and wherein the tuning structure comprises at least a portion of the metal plate corresponding to the opening.

16 . The MMU device of claim 14 , wherein the tuning structure is free of any screws and nuts of a tuning bolt.

17 . The MMU device of claim 14 ,
wherein the tuning structure comprises a see-saw structure, and wherein the cover plate comprises a fixator in a fixing region for balancing the see-saw structure.

18 . The MMU device of claim 17 , wherein a spatial arrangement of the tuning structure is determined by adjustment operations comprising at least one of a hit or a press applied to the see-saw structure.
