Procedure for Calculating Power Density of a Parabolic Circular Reflector Antenna

Herbert K. Kobayashi

Abstract: This technical report details a procedure for calculating the mainbeam off-axis power density in the near- and far-field of a parabolic circular reflector antenna. In the report, the on-axis procedures of an earlier report are extended to off-axis analysis. Like its predecessors, it is intended for general use in system planning and evaluation and gives a worst-case estimate for radiation hazard assessment.

Keywords: Antenna Field Intensity (AFI) Program; near-field off-axis power density; on-axis field intensity; parabolic reflector (circular)
