摘要：
A compact printed multiband decoupled dualantenna system for WWAN/LTE smartphone applications is presented. The proposed dual-antenna system is composed of two groups of symmetrical bending structures and uses the structure of the slotted and protruded ground to reduce the coupling between elements. A measured impedance bandwidth with S-11 lower than -6 dB over 740-965 and 1380-2703 MHz is obtained. The isolation between elements is better than 10 dB within the operating bands. Based on 3-D radiation patterns, the envelope coefficient, the mean effective gain, and the diversity gain are calculated. The results show that a good diversity performance is achieved for the proposed dual antenna, which makes the antenna suitable for WWAN/LTE smartphone applications.
