MULTI ANTENNA SYSTEM HAVING ANTENNAS OPERATING INDEPENDENTLY

摘要

A multiple antenna system is provided to improve efficiency of an antenna arrangement space by reducing the interval between antennas. A multiple antenna system includes a first radiator(110), a second radiator(120) and a first feeding unit. The first radiator of the mesh type forms a plurality of unit slots(10) in one surface of a substrate(20). Each unit slot has the size corresponding to the reference electromagnetic wavelength. The second radiator radiates the electromagnetic wave of the longer wavelength than the reference electromagnetic wavelength. The first feeding unit is formed on other surface of the substrate to pass the region corresponding to the center of the first radiator. The first feeding unit includes a first feeder(111-1) and a second feeder(111-2). The first feeder passes the region. The first feeder passes the region corresponding to the center of the first radiator. The second feeder passes the firsts radiator in a longitudinal direction of the first radiator.
