Design and Analysis of Compact CPW-Ultra Wideband Microstrip Patch Antenna for V2X, Sub-6GHz, and other Wireless Applications

Abstract

Contemporary advancements in communication systems engineering necessitate the creation of miniature antennas that provide superior performance across a wide spectrum of frequencies.  In this paper, it is constructed of a small-sized (coplanar waveguide) CPW wideband microstrip antenna. This antenna is constructed of a 50Ω feed line and a circular patch with radius 5.25mm etched on the small-size FR-4 substrate of mm³ with relative permittivity. The proposed antenna is capable of operating from 4 GHz to 13.19 GHz frequency with a 9.19 GHz bandwidth. The proposed antenna's gain can be observed at different frequencies. This antenna is appropriate for use in C, WiMAX, WLAN, 4G LTE, 5G midband, V2X, sub 6GHz, UWB, X, and Ku band. It is simulated by using ANSYS High Frequency Structured Simulations (HFSS) software. Experimental confirmation is provided for the simulation results.  To improve antenna parameters, including bandwidth and return loss, S₁₁, many types of slots are created in the ground plane
