MIMO dipole antenna with triple-band operation for LTE Femtocell access points

摘要

A novel triple-band three-port diversity dipole antenna for LTE access points is presented. The impedance bandwidths, determined from RL > 10 dB, can reach about 120 / 872 MHz (17.1 / 33.9 %) for the 700 / 2300 / 2500 MHz operating bands, respectively, which are covering the required bandwidth for LTE system. This proposed triple-band dipole array also provides maximum peak antenna gains and efficiencies of 4.8 / 7.4 dBi and 92 / 88 % across 700 / 2300 / 2500 MHz bands, respectively, with uni-directional radiation pattern in XZ- and YZ-plane.
