Title:
BASE STATION ANTENNAS HAVING AT LEAST ONE GRID REFLECTOR AND RELATED DEVICES
Document Type and Number:
WIPO Patent Application WO/2023/029431
Kind Code:
A1
Abstract:
Base station antennas include at least one passive 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 reflector and out a front radome of the base station antenna.
