The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transmission rate after a 4th generation (4G) communication system such as long-term evolution (LTE). An antenna in a wireless communication system may include: a plurality of antenna elements including a first antenna element and a second antenna element, the first antenna element and the second antenna element may include patch antennas, the first antenna element and the second antenna element may be disposed at a narrower interval than a reference interval, and the patch antenna may have an asymmetry structure.

First claim

What is claimed is:

1 . An antenna device in a wireless communication system, the antenna device comprising:
a substrate; a plurality of antenna elements disposed on the substrate, and comprising a first antenna element, a second antenna element, and a third antenna element, wherein each of the plurality of antenna elements has a rectangle shape and includes a first edge and a second edge longer than the first edge such that a vector component of a current flowing through each of the plurality of antenna elements is not oriented at 45 degrees to the second edge; and at least one feeding line for the first antenna element, the second antenna element, and the third antenna element, wherein a distance between a center of the first antenna element and a center of the second antenna element is shorter than a length corresponding to a half of a wavelength of polarized signals transmitted and/or received via the plurality of antenna elements, such that a first mutual coupling between the first antenna element and the second antenna element is formed, wherein a distance between the center of the second antenna element and a center of the third antenna element is shorter than the length, such that a second mutual coupling between the second antenna element and the third antenna element is formed, and wherein a sum of vector components of currents flowing through the plurality of antenna elements and corresponding to the polarized signals is oriented at 45 degrees to the second edge by the first mutual coupling between the first antenna element and the second antenna element, and the second mutual coupling between the second antenna element and the third antenna element.

2 . The antenna device of claim 1 , wherein the first edge is orthogonal to the second edge, and
wherein a ratio of a length of the first edge to a length of the second edge is determined based on a cross polarization ratio (CPR) of the plurality of antenna elements.

3 . The antenna device of claim 1 , wherein the first edge includes at least one opening portion along a longitudinal direction of the first edge.

4 . The antenna device of claim 3 , wherein at least one of a number of the at least one opening portion, a size of the at least one opening portion, or a shape of the at least one opening portion is determined based on a cross polarization ratio (CPR) of the plurality of antenna elements.

5 . The antenna device of claim 4 , wherein the at least one opening portion is quadrangular.

6 . The antenna device of claim 1 , wherein the first antenna element including an edge corresponding to the first edge and the second antenna element including an edge corresponding to the first edge are disposed such that the edge of the first antenna element faces the edge of the second antenna element.

7 . A massive multiple input multiple output (MIMO) unit (MMU) device, the MMU device comprising:
a substrate; a radio frequency integrated circuit (RFIC) disposed on the substrate; a plurality of antenna elements disposed on the substrate and comprising a first antenna element, a second antenna element, and a third antenna element, wherein each of the plurality of antenna elements has a rectangle shape and includes a first edge and a second edge longer than the first edge such that a vector component of a current flowing through each of the plurality of antenna elements is not oriented at 45 degrees to the second edge; and at least one first feeding line electrically connected with the RFIC for the first antenna element, the second antenna element, and the third antenna element, wherein a distance between a center of the first antenna element and a center of the second antenna element is shorter than a length corresponding to a half of a wavelength of polarized signals transmitted and/or received via the plurality of antenna elements, such that a first mutual coupling between the first antenna element and the second antenna element is formed, wherein a distance between the center of the second antenna element and a center of the third antenna element is shorter than the length, such that a second mutual coupling between the second antenna element and the third antenna element is formed, and wherein a sum of vector components of currents flowing through the plurality of antenna elements and corresponding to the polarized signals is oriented at 45 degrees to the second edge by the first mutual coupling between the first antenna element and the second antenna element, and the second mutual coupling between the second antenna element and the third antenna element.

8 . The MMU device of claim 7 , wherein the first edge is orthogonal to the second edge, and
wherein a ratio of a length of the first edge to a length of the second edge is determined based on a cross polarization ratio (CPR) of the plurality of antenna elements.

9 . The MMU device of claim 7 , wherein the first edge include at least one opening portion along a longitudinal direction of the first edge.

10 . The MMU device of claim 9 , wherein at least one of a number of the at least one opening portion, a size of the at least one opening portion, or a shape of the at least one opening portion is determined based on a cross polarization ratio (CPR) of the plurality of antenna elements.

11 . The MMU device of claim 10 , wherein the at least one opening portion is quadrangular.

12 . The MMU device of claim 7 , wherein the first antenna element including an edge corresponding to the first edge and the second antenna element including an edge corresponding to the first edge are disposed such that the edge of the first antenna element faces the edge of the second antenna element.
