Design of printed Yagi-antenna for 5G communication

This paper takes the monopole antenna as the active element of the printed Yagi-antenna. The antenna has the advantages of small weight, small size and good directivity. The optimal matching and gain of antenna are studied. The 50 Ω microstrip feed used in the active element. Simulation results show that the average gain is 6.9dBi at 3.4 ~ 3.6 GHz, S
₁₁
<; -10 dB up to 640 MHZ bandwidth at 3.24 ~3.88GHz. The return loss reached -36dB at 3.5GHz.Through the analysis of simulation data, the requirements of 5G communication antenna are satisfied.
