Abstract

This article proposes a compact novel 3‐dimension (3‐D) triple‐band antenna for mobile phone terminal equipments application. The first antenna, ANT 1, mainly contributes the regions of low frequency band. The second radiator; ANT 2, is to create the regions of high frequency band with the concept of coupling between the two antennas. The total volume of radiating element is 30 (L) × 5 (H) × 0.2 (W) mm^3^. The compact radiator has good characteristics of ratio of impedance bandwidth up to 33%. It is operated in three bands, 2.402–2 .4825 GHz, unlicensed NII—5 GHz UNII‐1 (5.125–5.25 GHz), and UNII‐2 (5.25–5.35 GHz) referring to the return loss −10 dB, respectively. The results of experiment are compared to numerical simulation can be agreement. The compact configuration as well as good electric characteristics of wide‐band can be achieved. © 2007 Wiley Periodicals, Inc.
