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.
