A method for modelling the radiation of an antenna under test from planar near-field data using equivalent magnetic currents (EMC) is presented. Micro-genetic algorithms are used to optimise each component of the EMC. Numerical results of near-field to far-field transformation are reported and discussed.

Inspec keywords: genetic algorithms; antenna radiation patterns; antenna theory; antenna testing; equivalent circuits

Other keywords: antenna far-fields; micro-genetic algorithms; numerical results; antenna under test; near-field to far-field transformation; planar near-field data; planar acquisition; equivalent magnetic currents; far-field pattern; antenna radiation modelling

Subjects: Antenna theory; Optimisation techniques
