BROADBAND GROUND RADIATION ANTENNA CAPABLE OF CONTROLLING RESONANT FREQUENCY BY USING METAL FRAME STRUCTURE

摘要

A broadband ground radiation antenna capable of controlling a resonant frequency using a metal frame structure is disclosed. The broadband ground radiation antenna capable of controlling a resonant frequency using a metal frame structure according to an embodiment include: a PCB which is formed on a body; a ground which is formed in a predetermined area of one side of the PCB; a metal frame which surrounds at least a part of the lateral side of the PCB; and a feeding structure which is formed between the metal frame and a feeding source of the PCB. The ground of the PCB is used as a radiator by the feeding structure. Accordingly, the present invention can obtain a broadband property.;COPYRIGHT KIPO 2017
