In recent Radio Frequency (RF) systems, optimized feeder lines are used to minimize signal loss and improve impedance matching. The paper designs an optimized feeder line for low-profile antennas using RF toolbox in MATLAB software. Conventional feed-based impedance matching techniques are often complex to design, and sometimes loss occurs due to impedance mismatch. For that external matching technique, i.e., quarter-wave transformer is essential. In addition, various parameters such as reflection coefficient, Voltage Standing Wave Ratio (VSWR), return loss and S11 are considered to determine the best impedance matching. RF toolbox provides a comprehensive set of functions and algorithms to design, analyze and optimize RF systems and circuits, including microstrip antennas and matching networks.


Rapidly growing technologies in the field of communication require high-performance antenna systems that can handle increasing data rates and frequencies. Microstrip antennas have gained popularity due to their low-profile and ease of integration with other components, making them ideal for various communication applications. Feeder lines play a crucial role in ensuring the optimal performance of these antennas by providing the necessary power to the antenna. However, designing a feeder line for a microstrip antenna requires careful consideration of impedance and matching to the
