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.
