ABSTRACT:
Disclosed herein is a multi-layered chip antenna using double coupling feeding. The multi-layered chip antenna comprises a first feeding radiation element including a first feeding electrode connected at one side of the first feeding electrode to a feeding line and connected at the other side thereof to a ground surface while being formed on a first plane in a predetermined direction, the first feeding radiation element being connected to the first feeding electrode so that the first feeding radiation element has a spatial meander line structure, a second feeding radiation element connected to a portion of the first feeding electrode on a second plane parallel to the first plane such that the second feeding radiation element has a planar meander line structure, a second feeding electrode connected to a portion of the first feeding electrode on a third plane parallel to the first plane, a first parasitic radiation element electrically coupled to the second feeding electrode, and a second parasitic radiation element electrically coupled to the second feeding electrode and comprising a plurality of parasitic patterns.
