Appendix G discusses the radiating E- and H-fields that surround an energized antenna, including radiation patterns versus separation distance from an antenna aperture. This material is supplemented by the accompanying website that contains example calculations using Mathcad for radiating near- and far-field patterns, where the Huygens-Kirchhoff formulation is used for the near-aperture radiating field calculations (Good 1990).
