METHOD FOR INSTALLING RADIATOR ELEMENTS ARRANGED IN DIFFERENT PLANES CAPABLE OF REDUCING PHASE DIFFERENCE OF RADIATION SIGNALS AND AN ANTENNA USING THE SAME

摘要

PURPOSE: A method for installing radiator elements arranged in different planes is provided to improve a radiation property of a second radiation device of a second frequency band while not degrading the radiation property of a first radiation device of a first frequency band.;CONSTITUTION: Patch type first radiator elements(11,12,13,14) of a first frequency band are arranged on a reflector(1) in a constant interval. Dipole type second radiation elements(21-27) of a second frequency band are overlapped on the first radiator elements. The first radiator element comprises upper patch plates(11-1,12-1,13-1,14-1) and lower patch plates(11-2,12-2,13-2, 14-2). The lower patch plate is connected to the printed circuit board through secondary feeder cables.;COPYRIGHT KIPO 2011
