A Procedure for Estimating the Power Pattern of a Narrow-Beam Antenna

In EMC analysis it is often required to assess the mutual interference between stations without detailed knowledge of the antenna patterns involved. Typically, only the mainbeam gain is available from large-scale spectrum-management data systems. This paper formalizes a simple method for estimating the power pattern of narrow-beam antennas from this admittedly insufficient information. Estimated patterns are compared with measured antenna patterns.
