A novel internal monopole antenna with integrated shielding case for application in mobile phone is presented. The proposed antenna module is constructed from a single metal plate that is folded into a shape that provides both a RF shielding case covers an RF front module and a dual-band monopole antenna applies for GSM and DCS band operating. By this high integration antenna design, the antenna will not need any more isolation distance for getting good impedance bandwidth, thus the antenna has a compact size and is placed closed to the RF shielding case. In this paper, the GSM/DCS dual-band internal monopole antenna has been realized into a mobile phone Nokia 3310, and the cost and size of the proposed antenna will be better than the original antenna design (planar inverted-F antenna) of Nokia 3310.
