This paper focuses on the design of a Wi-Fi antenna aimed at operating efficiently in the 2.4
GHz frequency band and the implementation of an impedance matching circuit integrated into it. The
impedance matching circuit was designed and integrated to operate the antenna, which does not operate at
the target frequency, at the target frequency. Coupling is carried out using a circuit called L matching,
which consists of a reactance and a susceptance element in the format jX and jB. AWR was used to design
the impedance matching circuit and check whether the required simulation results were achieved. The
antenna was designed in a simulation environment and then the designed matching circuit was integrated
into the numerical computation model of the proposed antenna. These tools played a critical role in the
paper in identifying and resolving issues with impedance matching and frequency alignment, ensuring the
antenna operated efficiently in the desired frequency range. The antenna performance has been significantly
increased, improving S11 parameter magnitude from 2.7dB to 30.1dB. The success of this study highlights
the importance of impedance matching in the development of high-performance antennas. By addressing
and overcoming initial challenges, the study not only achieved its primary goals but also provided valuable
information and methodologies that can be applied to future antenna designs. Integration of impedance
matching circuitry into Wi-Fi antenna design demonstrates the potential to improve the efficiency and
performance of wireless devices, making this research a valuable contribution to the field of
telecommunications.
