1. Field of the Invention
The present invention relates to a multi band chip antenna with dual feeding ports and a mobile communication apparatus using the multi band chip antenna, and more particularly to a multi band chip antenna, in which dual feeding ports are formed on a radiation electrode structure, thereby being usable at multi frequency bands, and a mobile communication apparatus using the multi band chip antenna.
2. Description of the Related Art
The above and other objects, features and other advantages of the present invention will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings, in which:
FIG. 1 is a schematic view illustrating a principle of operation of a conventional chip antenna;
FIG. 2a is a perspective view of a conventional chip antenna;
FIGS. 4a and 4b are a perspective view and a bottom view of a multi band chip antenna in accordance with a first preferred embodiment of the present invention, respectively. Hereinafter, with reference to FIGS. 4a and 4b, the multi band chip antenna of the first preferred embodiment of the present invention is described.
As shown in FIGS. 4a and 4b, the multi band chip antenna 40 of the first preferred embodiment of the present invention comprises a first conductive feeding port 43, a second conductive feeding port 44, a conductive power-feeding electrode 45 connected to the first feeding port 43, a conductive loop-type electrode 46 connected to the second feeding port 44, a conductive radiation electrode 47 electrically connected to the power-feeding electrode 45, a conductive ground electrode 48 connected to the radiation electrode 47, and a ground electrode port 49 connected to the ground electrode 48 and the loop-type electrode 46.
The second feeding port 44 is formed close to the first feeding port 43, thereby performing the electromagnetic coupling between the first feeding port 43 and the second feeding port 44. The first feeding port 43 is formed close to the ground electrode port 49.
