Abstract

The present invention relates to a multi-band, multi-polarized wireless communication antenna, which comprises: a reflector; at least one first radiation module of a first band which is installed on the reflector; and at least one second or third radiation module of a second band or a third band installed on the reflector, wherein the first radiation module comprises first to fourth radiating elements having a dipole structure, the first to fourth radiating elements are configured such that every two radiating arms thereof are connected in the shape of letter “ ”, one of the two radiating arms is configured to be placed side by side along side of the reflector, and the second or third radiation module is installed to be included within an installation range of the first radiation module.

First claim

What is claimed is:

1 . A multi-band multi-polarized wireless communication antenna, comprising:
a reflector; at least one first radiation module of a first band, which is installed on the reflector; and at least one second or third radiation module of a second or third band, which is installed on the reflector, wherein the first radiation module comprises first to fourth radiation elements having a dipole structure, each of the first to fourth radiation elements is configured such that two radiation arms are connected to each other in the shape of the letter “ ”, and one of the two radiation arms is configured to be placed along and parallel to a side the reflector, and wherein the second or third radiation module is installed to be included in an installation range of the first radiation module.

2 . The antenna of claim 1 , wherein the second or third radiation module is installed on upper and lower right surfaces and on upper and lower left surfaces within an installation range of the first radiation module.

3 . The antenna of claim 2 , wherein the reflector may be designed not to have an area substantially extending to the outside beyond an installation area of the first to fourth radiation elements of the first radiation module.

4 . The antenna of claim 1 , wherein one of fifth to eighth radiation elements, each of which is configured such that two radiation arms are connected to each other in the shape of letter “ ”, is included inside the first radiation module, and the fifth to eighth radiation elements may be installed to form a structure in the overall shape of letter “+”.

5 . The antenna of claim 1 , further comprising at least one 1-2th radiation module of the first band which is installed on the reflector, wherein the at least one 1-2th radiation module may be combined with the first radiation module so as to implement an antenna array of the first band.

6 . The antenna of claim 1 , wherein a feeding network is formed so that at least some of radiation elements catty-cornered from each other in the first radiation module are linked with each other to generates one among X polarized waves, respectively.

7 . The antenna of claim 1 , wherein the first to fourth radiation elements of the first radiation module forms a feeding network so as to generate first to fourth polarized waves, respectively.

8 . A multi-band multi-polarized wireless communication antenna, comprising:
a reflector; a first radiation module that is installed on the reflector and comprises first to fourth radiation elements having a dipole structure, wherein each of the first to fourth radiation elements is configured such that two radiation arms are connected to each other in the shape of the letter “ ”, and one of the two radiation arms is configured to be placed along and parallel to a side the reflector, and wherein the first to fourth elements of the first radiation module form a feeding network so as to generate first to fourth polarized waves, respectively.

9 . The antenna of claim 8 , wherein one of fifth to eighth radiation elements, each of which is configured such that two radiation arms are connected to each other in the shape of the letter “ ”, is included inside the first radiation module, and the fifth to eighth radiation elements may be installed to form a structure in the overall shape of the letter “+”.

10 . The antenna of claim 9 , wherein, when the fifth to eighth radiation elements are installed correspondingly to the first to fourth radiation elements respectively, the first and fifth radiation elements may be configured to be linked so as to generate a first polarized wave, the second and sixth radiation elements may be configured to be linked so as to generate a second polarized wave, the third and seventh radiation elements may be configured to be linked so as to generate a third polarized wave, and the fourth and eighth radiation elements may be configured to be linked so as to generate a fourth polarized wave.

11 . The antenna of claim 9 , wherein, when the fifth to eighth radiation elements are installed correspondingly to the first to fourth radiation elements, respectively, the first and seventh radiation elements may be configured to be linked so as to generate a first polarized wave, the second and eighth radiation elements may be configured to be linked so as to generate a second polarized wave, the third and fifth radiation elements may be configured to be linked so as to generate a third polarized wave, and the fourth and sixth radiation elements may be configured to be linked so as to generate a fourth polarized wave.
