Abstract :
The article deals with the Method of Moments used in analyzing the impedance of thin wire dipoles from current distribution. This is very practical interest, as realistic antennas can be modeled by wires whose radius is smaller than their length and the wavelength. The article introduces the Pocklington´s integral equation for thin straight wire and delta-gap source model. The equation is solved by the application of the moment method using pulse functions and point matching technique. The MATLAB script file was also created to introduce the results in a graphical manner. The results are compared with other references and professional simulation software.
