Low-Profile Wideband Conjoined Open-Slot Antennas Fed by Grounded Coplanar Waveguides for 4×4 5G MIMO Operation
Four grounded coplanar waveguide(GCPW)-fed open-slot antennas conjoined into a cross shape with a central circular slot are presented for 4×4 fifth-generation(5G)multi-input multi-output(MIMO)operation in 3.3-4.2 GHz.The four conjoined slot antennas have a 1 mm low profile(about 0.01λ at 3.3 GHz)and a compact size of 42 mm × 42 mm(about 0.46λ×0.46λ at 3.3 GHz)to provide four wide operating bands(about 24%centered at 3.75 GHz)with antenna efficiency better than 40%.The conjoined circular slot leads to enhanced operating bandwidth of the four slot antennas and good decoupling thereof.Owing to the 1 mm low profile,the conjoined slot antennas are promising to be integrated within the dielectric back cover of the 5G terminal device,thereby decreasing the antennas'volume inside the device.Details of the GCPW-fed conjoined slot antennas for 5G-MIMO operation are presented.
