New microstrip patch antenna array design at 28 GHz millimeter-wave for fifth-generation application

Abstract

<span lang="EN-US">This paper presents a study and an array design consisting of two microstrip patch antennas connected in series in a 2×1 form. This antenna provides better performance for the fifth-generation (5G) wireless communication system. The microstrip line feeding technique realizes the design of this antenna. This feed offers the best bandwidth, is easy to model, and has low spurious radiation. The distance between the feed line and the patch can adapt to the antenna’s impedance. In addition, the antenna array proposed in this paper is designed and simulated using the high frequency structure simulator (HFSS) simulation software at the operating frequency of 28 GHz for the 5G band. The support material used is Rogers RT/duroid® 5880, with relative permittivity of 2.2, a thickness of h=0.5 mm, and a loss tangent of 0.0009. The simulation results obtained in this research paper are as: reflection coefficient: -35.91 dB, standing wave ratio (SWR): 1.032, bandwidth: 1.43 GHz, gain: 9.42 dB, directivity: 9.47 dB, radiated power: 29.94 dBm, accepted the power: 29.99 dBm, radiation efficiency: 29.95, efficiency: 99.83%. This proposed antenna array has achieved better performance than other antenna arrays recently published in scientific journals regarding bandwidth, beam gain, reflection coefficient, SWR, radiated power, accepted power, and efficiency. Therefore, this antenna array will likely become an important competitor for many uses within the 5G wireless applications.</span>

Design of a 2×2 dual band 28/38 GHz MIMO antenna in millimeter band for 5G

“…Due to its low atmospheric absorption, this 28 GHz spectrum allows open space path losses comparable primarily to currently available cellular frequency bands (1-2 GHz). In addition, the reduction of rain-related effects as well as oxygen loss is low in the 28 GHz frequency band and provides more favorable conditions in this area than current cellular networks due to the presence or availability of scalable high-gain antennas as well as their cell size, which is at most 200 meters [20], [21].…”
