Abstract
Disclosed is a multi band chip antenna with dual feeding ports formed on a radiation electrode structure, thereby performing the electromagnetic coupling between the dual feeding ports and being usable at multiple frequency bands. Further, a mobile communication apparatus using the multi band chip antenna is disclosed. The multi band chip antenna comprises a first conductive feeding port, a second conductive feeding port, a conductive power-feeding electrode connected to the first feeding port, a conductive loop-type electrode connected to the second feeding port, a conductive radiation electrode electrically connected to the power-feeding electrode, a conductive ground electrode connected to the radiation electrode, and a conductive ground electrode port connected to the ground electrode and the loop-type electrode. The multi band chip antenna of the present invention is miniaturized, and the mobile communication apparatus using the multi band chip antenna does not require a diplexer.
