Title:Comparative Analysis of Different Feeding Techniques and Different Substrates on the Performance of 5G Micro-strip Patch Antenna
Abstract:Wireless communication is evolving rapidly to meet growing demands for higher data rates and seamless connectivity, especially with the rise of the Internet of Things (IoT). Among the latest advancements, 5G technology stands out by enabling ultra-fast  data  transmission,  high  capacity,  and  efficient  spectrum  utilization  through  millimeter-wave frequencies. This study presents a comparative analysis of six Microstrip Patch Antennas (MPAs) designed for 5G applications, addressing the challenge of limited spaceand increasing performance  demands.  The  novelty  of  this  work  lies  in  the  evaluation  of  how  substrate materials  and  feeding  techniques  influence  MPA  performance,  providing  insights  not thoroughly addressed in prior research. The antennas were designed using three substrates1:FR-4 (εr = 4.4), 2-Rogers RT5880 (εr = 2.2), and 3-Taconic  RF-35TC (εr =3.5), and  two feeding techniques: Microstrip line feed and coaxial probe feed. All antennas were tuned to resonate  at  38  GHz,  suitable  for  5G  millimeter-wave  applications. Feeding technique  also significantly  affects  impedance  matching  and  Gain.It  is  found  out  that  using  Roggers  RT Duroid 5880 substrate with Microstrip feedline technique provides the highest gain whereas the  largest  bandwidth  is  achieved  using  coaxial  feed  with  FR4  substrate.A  quarter-wave transformer  was  additionally  implemented  for  optimal  impedance  matching  between  the source and antenna. The findings guide substrate and feed selection in compact 5G antenna designs.
