Accurate Current Distribution of Dipole Antenna using Pocklington’s Integral Equation

Abstract: In a dipole antenna, the current distribution is usually assumed to be of sinusoidal form. For finite diameter wires the sinusoidal current distribution is representative but not accurate. To find a more accurate current distribution on a dipole, pocklington’s integral equation is usually derived and solved. For the wire antenna by previously, solutions to the integral equation were obtained using iterative methods. Presently, it is most convenient to use Pocklington’s integral equation techniques. Some mathematical formulation is being done and shown with help of MATLAB. If we know the voltage at the feed terminals of a dipole antenna and find the current distribution, the input impedance and radiation pattern can then be obtained.
