5G mm-Wave MIMO Antenna with Beam Switching Capabilities Fabricated Using 3D Printing

This paper presents a MIMO antenna for 5G mm-wave applications. The proposed MIMO is capable of providing continues beam cover in the elevation for up to ± 30° without using phase shifters. The proposed MIMO is fabricated using 3D printing and it has good measured performance over wide band. The proposed MIMO operates at 28 GHz 5G band with a measured bandwidth of more than 4 GHz and a measured peak gain of higher than 10 dBi.
