Y-shaped Triple-band Microstrip Patch Antenna for 5G Millimeter-wave Applications

Due to appear new applications such as information showering and the vehicular applications that demand a high data rate, better bandwidth utilization, and good quality of service (QoS) in wireless communication systems, that can only be achievable in Fifth Generation (5G). This paper proposes compact triple-band Y-shaped microstrip patch antennas (MPAs) for 5G applications. The proposed antenna has a dimension of $5 \times 5 \times 0.381$ mm3, uses Rogers/ RT Duroid 5870 as a substrate material, and a loss tangent of 0.0012. The Defected ground structure (DGS) in the middle and groove at the top of the ground plane was implemented. This achieves -10 dB bandwidth from 29.55-30.72 GHz with a maximum gain of 6.834 dB, from 57.36-63.34 GHz with a maximum gain of 10.196 dB, and from 68.56-94.281 GHz with a maximum gain of 8.628 dB at resonant frequencies 30.1 GHz, 60 GHz, and 81.3 GHz respectively. The proposed antenna has a high gain and a broad bandwidth making it a candidate for 5G millimeter-wave (mmwave) applications. Higher Frequency Structural Simulator (HFSS v13) tool is used to simulate the proposed antenna.
