Design of 12-Port MIMO Antenna for 5G Communication in Mobile Handset

Abstract: A compact 12-port MIMO antenna system is proposed. This system consists of eight stereoscopic inverted F antenna and four inverted F antenna : The 1—4# antenna element and 5—8# antenna element are mainly used for 5G communication and the impedance bandwidth can cover 3300~3600 MHz. The 9—12# antenna element is a supplement to mainly cover the 5G communication spectrum of 4800~5000 MHz. The isolations of the low band and high band of this MIMO antenna system are higher than 12 dB and 19 dB respectively. Moreover, this system has higher gain and radiation efficiency at low band and high band.
