Abstract :
A novel compact wideband planar diversity antenna for mobile terminals is proposed. It has a -10 dB impedance bandwidth from 1.904-2.504 GHz including UMTS (1.920-2.170 GHz) and 2.4 GHz WLAN (2.400-2.484 GHz) bands. The mutual coupling of the diversity antenna is below -15 dB in the whole band (about -20 dB in most of the band). The diversity performance is also evaluated by calculating the correlation coefficient and the diversity gain. The user´s hand effects on both the bandwidth and the mutual coupling have been analyzed by simulation with a simple hand model and measurement.
