Design of MIMO Antennas for 5G C-band/WLAN Operation in the Laptop Computer

The paper presents a design of 5G C-band and WLAN MIMO antennas for laptop computers. There are two sets of MIMO antennas operating at 5G C-band with a loop antenna operating at WLAN and acting as an isolation device between two sets. The set of MIMO antennas is designed with a coupled-fed meandered loop located at the top edge of the display ground. Loop antenna is placed between two sets of MIMO antennas. The MIMO antennas can cover the 5G C-band (3.3-3.8 GHz). The loop antenna resonates the band of WLAN. The MIMO antennas size is 12 × 75 × 4 mm

and the loop antenna size is 15.8. × 15.8 mm

. And the antennas implemented on 0.8mm thick substrate of FR-4. The size of the system ground made of copper sheet with a thickness of 0.1 mm is 200 × 310 mm
