MULTI-BAND ANTENNA CAPABLE OF MAKING A COUPLING EFFECT OF A DIPOLE SHAPE BY A SINGLE ANTENNA

摘要

PURPOSE: A multi-band antenna is provided to miniaturize an antenna without the drastic reduction of the gain and efficiency of the antenna.;CONSTITUTION: A first radiating object(10) connects one end with a ground unit(40) and connects the other end with an electricity supply unit(30). A second radiating object(20) connects one end with the ground unit and opens the other end. Electricity is supplied to a multi band antenna(1) through the first radiating object. A folded part(12) of the first radiating object and a folded part(22) of a second radiating object are separated symmetrically around a coupling area(50).;COPYRIGHT KIPO 2011
