Recently, microstrip patch antennas have gained significant popularity in the
field of Internet of Things (IoT) applications owing to their advantageous
characteristics such as their compact form factor, cost-effectiveness, and ease of
manufacturing. This study presents an analysis of the radiation characteristics and
efficiency of MPAs (Microstrip Patch Antennas) in the context of IoT (Internet of
Things) applications. The objective of this study is to enhance and gain insights into
the impact of various design factors through the utilization of two widely employed
feed methodologies, namely microstrip line feed and coaxial probe feed. The antenna
was designed and simulated to operate at a resonant frequency of 2.4 GHz. This was
achieved by utilizing a TLY series dielectric substrate with a dielectric constant of
around 2.17 and a thickness of 1.6 mm. The evaluation of the antenna performance
was conducted using the Computer Simulation Technology (CST) microwave studio
software. The antennas under consideration have demonstrated a reflected coefficient
of -28.5 dB and -10.30 dB when utilizing microstrip line feed and coaxial probe feed,
respectively. The simulation yielded favorable outcomes for VSWR, directivity,
gain, bandwidth, and efficiency. In comparison to previous designs reported in the
literature, the antenna being presented exhibits a significant enhancement in
directivity, beam gain, return loss, and high radiation efficiency
