Abstract

A wideband printed dual-antenna for mobile terminals is presented. The antenna array consists of two symmetric antenna elements, A T-shape protruded ground(TP) and three slots. The antenna element consists of a feed strip and two radiation strips(RS1, RS2), which only occupies a planar size of 15 × 25mm2. The three slots and T-shape metal strip are utilized to reduce the mutual coupling. Different slot can adjust different frequency band independently. The working mechanism of the three slots is analyzed based on the S-parameters and surface current distributions. A measured impedance bandwidth with S11 lower than 6 dB over 824 960MHz and 1710-2690 MHz is obtained. Within the operating bands, the measured S21 is lower than -15dB. The radiation patterns are measured, and the diversity performance is presented.
