Abstract

The design of an eight-port MIMO antenna at the sub-6-GHz(LTE 42/43 and 46)bands for fifth-generation(5G) smartphone is presented. First,based on the Babinet’s principle, a microstrip slope antenna (MSA) is designed from its counterpart complementary structure, microstrip patch antenna (MPA) to operate over the LTE 46 band. The IFAs are additionally equipped with a parasitic radiating element that allows them to operate at the specific three LTE bands,a proposed single antenna, namely RMS, is achieved. For MIMO operation, two antennas are mounted on a practical PCB (100–40). When shifting their location on the PCB, several antenna layouts are tested. Simulated and experimental results are conducted to examine the performance of the designed MIMO antenna. Good isolated, acceptable gain, and efficiency are obtained over the bands of interest which verify the suitability of the proposed system for MIMO smartphone applications.
