PRINTED CIRCUIT BOARD TYPE ANTENNA, CAPABLE OF BEING MINIATURIZED USING THE CHARACTERISTIC OF A MONOPOLE ANTENNA AND A COUPLER

摘要

PURPOSE: A printed circuit board type antenna is provided to reduce the length of a conductor in the antenna by additionally installing the coupler of a capacitor on the rear side of the dielectric substrate of a monopole antenna.;CONSTITUTION: A conductive pattern(3) is applied on the upper side of a dielectric substrate(1). A current feeding point(5) is formed around the conductive pattern. A coupler(7) reduces a received signal from a high frequency band to a low frequency band. A ground plane is formed on the lower side of the coupler and the current feeding point. A ground pad(11) is formed on the ground plane and the current feeding point in order to be in contact with a coaxial cable.;COPYRIGHT KIPO 2011
