Abstract: In this paper, a 3D-printed dual-band reflect-transmit-array (RTA) antenna has been presented, which operates as a reflectarray (RA) in the 28 GHz band and as a transmitarray (TA) in the ...

To fully exploit the array and multiplexing gains, beamforming or precoding strategies require accurate information about the multiple multipath components (MPCs) in the mmWave channel. In this paper, ...
