Design and Simulation of Antipodal Vivaldi Antenna (AVA) AT 2.6 GHz For 5G Communication Optimation

Abstract

The evolve of communication are growing rapidly, people competing to make communication much better than before, the technology develop is 5G communication, the data rate and speed that 5G given more better than 4G. Every communication technology requires an antenna as a transmitter and receiver to support communication working properly. Antipodal Vivaldi (AVA) is one type of Vivaldi Antenna which is better than other types of Antipodal Vivaldi for 5G communications. It has advantages for the High Gain, improve return loss, high efficiency, enhanced beamwidth, low sidelobe level, (Reduce the sidelobe level and back lobe level), Compact size, Stable radiation pattern, higher Operating Frequencies (1 Ghz to 100 Ghz) and more front to back ratio, which are really suitable for 5G communications. Antipodal Vivaldi Antenna (AVA) work at 2.6 GHz (2.6768 Ghz). The antenna needs to get the Institute of Electrical and Electronics Engineers (IEEE) defined standards which is VSWR 1, reference impedance 100 ohm, and s- parameter below -20dB. The Antipodal Vivaldi Antenna design process is carried out by using math formulation and experimental methods. For simulate and optimizing it, it uses CST studio suite 2018 software. To get the IEEE defined standards, AVA need to be optimize with changing antenna dimension elements (feed line width) and conFig. its slots which can lead to physic optimization. The results obtained in the form of slot antenna that works at a frequency of 2.6 GHz (2.6768 Ghz). The results obtained are the value of slot antenna. VSWR has a value of 1.0508971. The return loss is -32.105013. The gain is about 2.697 dB. The antenna has a line impedance of 100 ohm.
