Analysis of Half-Wave Dipole Antenna Current Characteristics Using the Moment Method (Pocklington)

The Moment Method (Pocklington) can be employed to analyze the current characteristics and radiation pattern of half-wave dipole antennas. As a mathematical technique, the Moment Method investigates antenna performance by computing the relationship between current distribution and electromagnetic field distribution. Through the application of this method, we can understand the radiation properties and directional characteristics of half-wave dipole antennas across different frequencies. The implementation typically involves discretizing Pocklington's integral equation, where the antenna structure is divided into segments, and basis functions are used to represent current distribution. Key computational steps include matrix formulation using method of moments, solving linear equations for current coefficients, and calculating far-field patterns through integration. This analytical approach helps optimize antenna design to achieve superior performance within specific frequency ranges.
