ABSTRACT:
Disclosed is an antenna apparatus for a portable terminal which includes radiation elements received in a housing of the portable terminal; contact arms formed on the radiation elements; and feeding pads disposed on both surfaces of a printed circuit board, wherein the contact arms are in contact with the feeding pads. The contact arms respectively come in contact with each feeding pad. The pair of feeding pads is attached to the printed circuit board while the contact arms are provided on the radiation elements so as to come in contact with the each feeding pad, so that the antenna apparatus may satisfy operation criteria of wide and multi bands. In addition, the radiation elements are formed as a pair, one of which satisfies the operation criteria of double and triple bands and the other of which has resonance frequency of other bands, so that the operation criteria of the multi bands can be effectively achieved.
