Planar triple-band MIMO dipole antenna for LTE /WLAN access points

摘要

A novel triple-band three-port diversity dipole antenna for LTE / WLAN access points is presented. The impedance bandwidths, determined from RL > 10 dB, can reach about 1763 / 795 MHz (52.4 / 14.1 %) for 2500 / 3500 MHz and 5200 / 5800 MHz operating bands, respectively, which are covering the required bandwidth for LTE /WLAN system. This proposed triple-band MIMO dipole antenna also provides maximum peak antenna gains and efficiencies of 7.5 / 7.8 / 7.5 dBi and 87 / 89 / 88 % across 2500 / 3500 / 5500 MHz bands, respectively, with uni-directional radiation pattern in XY-, XZ- and YZ-plane.
