In order to increase the impedance bandwidth for wireless local area network (WLAN) applications, a
unique design of a microstrip line-fed, capacitively coupled, corner-truncated microstrip patch antenna is
put forth, examined, and optimized in this research. The low profile, light weight, ease of manufacture,
and compatibility with printed circuit technologies of microstrip patch antennas are well known.
Conventional patch antennas’ intrinsically small impedance bandwidth, however, is a significant
disadvantage that reduces their usefulness in broadband wireless communication systems. The current
work presents a methodical design strategy that combines sophisticated feeding strategies with structural
alterations to overcome this limitation. An equivalent circuit model that highlights the underlying
resonance characteristics is created, examined, and presented in order to obtain a fuller understanding of
the behavior of the suggested antenna. The antenna achieves a consistent radiation performance and a
significantly broad impedance bandwidth of around 6.27%, according to simulation and analysis.
Additionally, the antenna has a 5.66 dBi peak gain, which makes it a viable option for dependable
WLAN applications where gain, bandwidth, and compactness are crucial factors. To verify the
underlying resonance behavior, an equivalent circuit model of the suggested structure is created and examined. The antenna achieves a peak gain of 5.66 dBi and a broad impedance bandwidth of roughly
6.27% with steady performance, according to simulation data. These findings are in good agreement with
those of other small broadband microstrip antennas that have been documented in the
literature.Therefore, by increasing bandwidth while maintaining simplicity and compactness, the
suggested design provides a well-rounded solution that is ideal for WLAN systems and flexible enough
to accommodate additional wireless applications that demand fast and effective operation.Because of
these features, it is ideally suited for WLAN applications where compact antenna integration, fast data
rates, and dependable coverage are essential. Crucially, the outcomes are in line with and sometimes
better than similar broadband antenna designs documented in the literature, which frequently depend on
more intricate geometries, multilayer substrates, or extra parasitic components.
