Abstract	The Friis transmission equation is a fundamental principle of radio engineering. It is a method for studying radio wave propagation. It helps to calculate the power received by an antenna considering both the distances between its antennas and the characteristics of both antennas. To comprehend and improve WPT systems, it is essential to utilize this equation, particularly for long-range scenarios. Using the CST Microwave simulation software, this paper co nducts a study to verify the validity of the Friis transmission formula for far-field radio wave analysis.
