Abstract
Base station antennas include at least one internal grid reflector, with an array of low band radiating elements projecting forward of a front one of the at least one grid reflector. A mMIMO antenna array resides behind a back one of the at least one grid reflector and is configured to transmit signal through the grid and out a front radome of the base station antenna.
