Series fed Circular patch Antenna 3x1 array for C Band Applications

Abstract

This paper presents an array of series coaxial feeding microstrip antennae with three circular patch elements at resonant frequency 5.8 GHz for the ISM band having a return loss (S11) of -14.95 dB. The designed antenna has a property of radiation pattern having directive gain 3.21dB and BW is 210 MHz ANSYS electromagnetics suite and HFSS are used to simulate the proposed antenna's gain, radiation pattern, return loss, and parametric optimizations. The proposed circular microstrip antenna array is aimed to use for C-band wideband applications like monitoring of weather (climate), medical, and ATC, to regulate traffic on maritime vessels, defense monitoring, and detection of the velocity of vehicles for law enforcement. © 2023 IEEE.
