ELDS), NUMERICAL ANALYSIS, DIPOLE ANTENNAS, ANTENNA ARRAYS, ANTENNA RADIATION PATTERNS, RADIATION HAZARDSNEAR FIELD, THIN WIRE ANTENNAS, METHOD OF MOMENTSThe method of moments is applied to wire antenna near-field problems. A numerical method for the computation of near electric and magnetic fields of thin-wire antenna structures is described. Details of the method are included, together with examples of its application to various problems of engineering interest. Comparative studies of typical near-field problems indicate results to be accurate as close as the length of one subsection from the wire surface, or as close as 3 to 5 wire radii. Methods for checking near-field computations are described. The selective use of a Hertzian dipole model reduced computation time considerably (15/1) without sacrifice of accuracy. The near fields of a half-wave dipole and of arrays (broadside and endfire) are described in detail. The near fields of an array and resultant radiation hazards are significantly affected by mutuals. The near-field polarization ellipse is characterized. (Author)
