Abstract

Embodiments of the present disclosure provide an antenna device and a base station comprising the same. The antenna device may comprise an antenna array with a radiation pattern including a main lobe and a back lobe; and a first reflector able to be configured to reflect a first part of energy of the back lobe to at least one direction different from a direction of the main lobe.

First claim

What is claimed is:

1. An antenna device, comprising:
an antenna array with a radiation pattern including a main lobe and a back lobe;
a first reflector configurable to reflect a first part of energy of the back lobe to at least one direction different from a direction of the main lobe; and
a second reflector configurable to reflect a second part of energy of the back lobe to a direction of the main lobe.

2. The antenna device according to claim 1 , wherein the first part of energy of the back lobe is from 0% to 100% of the energy of the back lobe.

3. The antenna device according to claim 1 , wherein at least one of an orientation, a shape and a dimension of the first reflector are able to be adjusted manually or automatically.

4. The antenna device according to claim 1 , wherein the direction different from the direction of the main lobe comprises a direction toward sky.

5. The antenna device according to claim 1 , wherein the first reflector includes one of a metal plate, a wire mesh, parallel wires or metal bars.

6. The antenna device according to claim 1 , wherein the first reflector includes a plurality of reflector elements each of which comprises one of a metal plate, a wire mesh, parallel wires or metal bars.

7. The antenna device according to claim 1 , wherein the energy of the back lobe consists of the first part of energy of the back lobe and the second part of energy of the back lobe.

8. The antenna device according to claim 1 , wherein at least one of an orientation, a shape and a dimension of the second reflector is able to be adjusted manually or automatically.

9. The antenna device according to claim 1 , wherein the second reflector includes one of a metal plate, a wire mesh, parallel wires or metal bars.

10. The antenna device according to claim 1 , wherein the second reflector includes a plurality of reflector elements each of which comprises one of a metal plate, a wire mesh, parallel wires or metal bars.

11. The antenna device according to claim 1 , wherein at least a part of the first reflector is configured to reflect a part of energy of the back lobe to the direction of the main lobe and the at least a part of the first reflector is set in a same plane as the second reflector.

12. A base station comprising:
an antenna device, configured to at least one of transmit and receive a radio frequency (RF) signal; wherein the antenna device comprising:
an antenna array with a radiation pattern including a main lobe and a back lobe;
a first reflector configurable to reflect a first part of energy of the back lobe to at least one direction different from a direction of the main lobe; and
a second reflector configurable to reflect a second part of energy of the back lobe to a direction of the main lobe.

13. The base station according to claim 12 , wherein at least one of an orientation, a shape and a dimension of the first reflector are able to be adjusted manually or automatically.

14. The base station according to claim 12 , wherein the direction different from the direction of the main lobe comprises a direction toward sky.

15. The base station according to claim 12 , wherein the first reflector includes one of a metal plate, a wire mesh, parallel wires or metal bars.

16. The base station according to claim 12 , wherein at least one of an orientation, a shape and a dimension of the second reflector is able to be adjusted manually or automatically.

17. The base station according to claim 12 , wherein the second reflector includes one of a metal plate, a wire mesh, parallel wires or metal bars.

18. The base station according to claim 12 , wherein at least a part of the first reflector is configured to reflect a part of energy of the back lobe to the direction of the main lobe and the at least a part of the first reflector is set in a same plane as the second reflector.

19. The base station according to claim 12 , wherein the base station is used in indoor scenario.
