Document Type and Number:

Japanese Patent JP2012044298

Kind Code:

A

Abstract:

To provide a radio communication system which can downsize a transmission array antenna and a reception array antenna used for near MIMO transmission without deteriorating communication quality.

A radio communication system comprises: a transmission device including a transmission array antenna comprised of a plurality of transmission antenna elements for transmitting a signal; and a reception device including a reception array antenna comprised of a plurality of reception antenna elements each of which receives the signal transmitted from the transmission device and forms a pair with any one of the transmission antenna elements. Each of the transmission antenna elements is allocated a polarization characteristic different from an adjacent transmission antenna element and each of the reception antenna elements is allocated the same polarization characteristic as a transmission antenna element which forms a pair.
