Abstract
In the rapidly advancing landscape of wireless communication technology, there
is a pressing need for antennas that are compact, lightweight, cost-effective, and
have a low profile. Microstrip patch antennas have emerged as popular choices in
numerous wireless communication applications due to their inherent benefits such
as lightweight, compact size, affordability, ease of fabrication, and high reliability.
However, these antennas encounter challenges, notably in the form of narrow
bandwidth and low gain.
Various design factors influence the radiation properties of microstrip antennas,
encompassing feeding techniques, substrate materials, patch configuration, and
ground structures. This thesis is devoted to addressing the limitations of narrow
bandwidth and low gain in microstrip patch antennas, specifically tailored for 5G
mobile communication.
In this study, we enhanced a microstrip patch antenna’s design to boost performance
for 5G applications. By carefully adjusting its dimensions, the antenna
achieved a bandwidth of 7.64% (2140 MHz), a return loss of -39.388 dB, and a
VSWR of 1.021. These results show that our method significantly enhances the
antenna’s performance compared to previous designs, making it more effective for
5G communication.
