1. An antenna device comprising:
- a circuit board;
at least four antenna elements wherein a first two antenna elements are disposed, along one end of the circuit board, symmetrically to each other about both wide surfaces of the circuit board, and a second two antenna elements are disposed, along the other end of the circuit board, symmetrically to each other about the both wide surfaces of the circuit board; and
a feeding controller which feeds power selectively to at least one of the four elements,wherein the circuit board is configured to reflect an electromagnetic wave generated from at least one of the four antenna elements.

16. An antenna device comprising:
-
a circuit board; at least four antenna elements wherein a first two antenna elements are disposed, along one end of the circuit board, symmetrically to each other about both wide surfaces of the circuit board, and a second two antenna elements are disposed, along the other end of the circuit board, symmetrically to each other about the both wide surfaces of the circuit board; and a feeding controller which feeds power selectively to at least one of the four elements, wherein, if the power is fed to only one of the first two antenna elements or only one of the second two antenna elements, a first beam pattern having a peak at 90°
, perpendicular to the wide surfaces of the circuit board, is generatedwherein, if the power is fed to only the other of the first two antenna elements or only the other of the second two antenna elements, a second beam pattern having a peak at 270°
, which is in an opposite direction to the first beam pattern, is generated, andwherein, if the power is fed to both of the first two antenna elements or both of the second two antenna elements, a third beam pattern having a peak at 180°
, which is in a direction toward a side of the circuit board, is generated.
