Claim 4:
5. A transceiver comprising:
A Multiple-Input and Multiple-Output (MIMO) antenna including a substrate, and transmission antenna elements and reception antenna elements separately coaxially disposed on the same plane of the substrate;
an RF switch for changing polarization of each polarization characteristic of the MIMO antenna; and
a distributor for distributing power of the transmission antenna elements and the reception antenna elements such that a phase of a signal transmitted from the MIMO antenna is controlled,
wherein among antenna elements disposed outside a coaxial structure of the MIMO antenna, a pair of transmission antenna elements disposed in a first quadrant and a third quadrant of the substrate are inclined left and symmetric to each other and another pair of transmission antenna elements disposed in a second quadrant and a fourth quadrant of the substrate are inclined right and symmetric to each other, and
wherein among antenna elements disposed inside the coaxial structure of the MIMO antenna, a pair of reception antenna elements disposed at an upper portion and a lower portion on the substrate are inclined right and symmetric to each other and another pair of reception antenna elements disposed at a left portion and a right portion on the substrate are inclined left and symmetric to each other.
