An Eight-Port Dual-Band Antenna Array for 5G Smartphone Applications

A compact MIMO dual-band (3.45 / 4.9GHz) antenna array for future 5G smartphone is presented in this paper. The array consists of two symmetric 4-antenna arrays disposed in the narrow spacing between the display panel and the long side edges and four corners of the smartphone. The simulated result shows that the presented antenna has dual-band at 3.3-3.6 GHz and 4.8-5.0 GHz, which has a bandwidth of 300 MHz and 200 MHz respectively for reflection coefficient less than -6dB, and an acceptable isolation (better than -13.75 dB) are obtained. Envelope correlation coefficient are calculated to evaluate the MIMO performances of the proposed antenna array.
