摘要

A wideband printed dual-antenna system for mobile terminals is presented. The dual-antenna, consisted of two symmetric antenna elements and a neutralization line (NL), is printed on a printed circuit board. The antenna element is an F-like monopole with a grounded branch. The working mechanism of the dual-antenna is analyzed based on the { S}-parameters and the surface current distributions. A prototype shows the measured-10-dB impedance bandwidth is 1.09 GHz (1.67-2.76 GHz) and the measured mutual coupling is lower than-15 dB at the 1.7-2.76-GHz bands. It covers the GSM1800, GSM1900, UMTS, LTE2300, LTE2500, and 2.4-GHz WLAN bands. The radiation patterns are measured, and the diversity performance is evaluated.
