Eight-Port Massive MIMO Antennas of USB Device for 5G C-Band

The eight-port massive MIMO antennas of USB device for 5G C-band is proposed and investigated. The overall size of the design is 71 × 28 × 5.8 mm3. The design is implemented on the FR4 substrate with permittivity of 4.4 and thickness of 0.8 mm. The antennas are designed with open slot structures on the metal frame and the parasitic elements with cross shaped strips are placed in the middle of the antenna as the isolation mechanism. According to the results, The S parameters are all less than -10 dB with the 5G C-band and the isolations are all larger than 10 dB and the ECC are all less than 0.3. The design could be applied the band of 5G C-band and good performances is good for application of USB dongle devices with 8 × 8 massive MIMO antennas.
