New Design of 60-GHz Quasi-Yagi and Stacked Series Planar Antenna Array for 5G Wireless Application

In this paper, two new 60 GHz antennas design are successfully performed, including a single patch antenna and MIMO antennas with 2X2 and 2X6 elements for a 5G wireless communication network. The proposed Quasi-Yagi antenna size was 7.1 mm ×2.6 mm and stacked series planar was 13.85 mm ×1.8 mm and were printed on 0.787 mm-thick Rogers Duroid RT5880 substrate with dielectric constant of = 2.20 and loss tangent (tan δ) of 0.0002. Both antennas were designed and simulated using CST Microwave software and operated at 60 GHz. All proposed antenna-elements showed a very consistent return-loss (S11) characteristic, the bandwidth impedance of 4.61 GHz and 8 GHz were obtained for Quasi-Yagi antenna and stacked series planar antenna, respectively. The return loss reached more than −25 dB at 60 GHz, and the gain reached 5 dB.
