Abstract： Aiming at the requirements of multi-band，simple structureand high isolation ofMIMO antenna for wireless intellgentterminals，thispaperstudiesandproposesabroadbandMMOantennadesignfor5Gsmartphones.Theantenauses metal plate slotting technology to achieve dual-band resonance.It is fed from the bottom through a 50Ω coaxial line，and eight L-shaped patch units withmirrorsymmetryare excited toradiate the slots to forman 8-Element MIMOantenna.The antenna covers5GN77/N78/N79bands（ 3.3～4.2 GHz， 3.3～3.8 GHz， 4.4～5.0GHzΩ .Through the optimization of three-dimensional electromagneticsimulationsoftwareHFSSandthetestofphysicalproduction，theresultsshowthattheretumlossoftheantea in the target frequency band is less than -6dB ，theisolation between ports is better than -11.7 dB，and the Envelope Correlation Coeficient （ECC）is lessthan 0.06， which mets the performance requirements of5Gcommunicationsystem. Compared withthe traditionalantea，theanteadesignhasthecharacteristicsofsimplestructureandwidefrequencyband，whichisstablefor the compact space requirements of modern smartphones.
