Abstract

This project focuses on the designs of a microstrip patch antenna with implementation of 2x1 array using CST Studio Suite 2022. The primary objective is to enhance the performance of the antenna by utilizing an array configuration with different inset-feedline dimension, where 2x1 array is the subsequent design from single microstrip patch antenna. The operating frequency chosen for this study is 2.45 GHz and the antenna substrate material employed is FR-4, with a dielectric constant of ɛr = 4.3. The dimensions of the microstrip patch array antenna are (63.4 x 113.7 x 1.6) mm2 . The simulation results serve as a benchmark for assessing the effectiveness of the array implementation. Furthermore, the fabricated antenna undergoes a rigorous validation process by comparing the results obtained from the fabrication with the simulation outcomes. This comparison allows for an assessment of the practicality and reliability of the design. It was found that implementation of 2x1 array configuration has successfully improved the performance compared to single microstrip patch antenna. In terms of return loss, S11 (-11.64 dB to -17.95 dB) improved by 54.18% at 2.45 GHz, gain improvement (2.58 dBi to 5.06 dBi) by 96.12%, and bandwidth frequency, (63 MHz to 108 MHz) improved by 71.43%.
