Compact and Wide Bandwidth Microstrip Patch Antenna for 5G Millimeter Wave Technology: Design and Analysis

Abstract

In this paper, a compact microstrip patch antenna for 5G Millimeter wave technology has been proposed. By developing wide bandwidth characteristics, long ranges of data transfer are covered with better quality of signal transmission in 5G communication system. Modification of antenna element; patch width structured has influenced the frequency bandwidth. The design, analysis and optimization of the proposed work along with parametric analysis were performed using CST Microwave Studio. A microstrip patch antenna has been designed with high bandwidth millimeter wave, compact dimension, consistent radiation patterns and relatively higher gain at 28 GHz (mm-wave) band. FR-4 substrate has been employed in this work with a dielectric constant value of 4.3, thickness value of 1.6 mm and loss tangent value of 0.025.The proposed antenna has achieved high bandwidth which is 14.674 GHz with a reflection coefficient of -40.14 dB, Voltage Standing Wave Ratio (VSWR) value of 1.1098 dB and maximum gain of 5.29 dB with high directivity of 7.465 dBi. The antenna results of this work proved to be useful in fulfilling the requirements of wider bandwidth and higher gain particularly at 28 GHz for 5G applications.
