Abstract

5G has been planned to meet the strong data advancement and accessibility of the present society. In the proposed work, a new rectangular antenna that has high bandwidth millimeter-wave, stable radiation patterns, and improved reflection coefficient at 28 GHz for future 5G applications, has been designed and fabricated. The FR-4 substrate having a very compact dimension (5.5× 4.35) mm2 with a dielectric constant of 4.4, the thickness of 1.6 mm and loss tangent of 0.002 is used for the design and fabrication of the proposed antenna. The proposed configuration has been designed and simulated by using HFSS (High-Frequency Structure Simulator) simulator which is based on the finite element method. The impedance bandwidth achieved by the designed antenna is about 4.10 GHz (25.8 GHz–29.9 GHz) and has a reflection coefficient of about -39.70 dB, with a maximum gain of 5.32 dBi. The measurement results are in good agreement with the simulated results.
