Abstract

Regarding a microstrip trace above an infinite ground plane, near field and far field regions are clearly defined for near field-far field conversion. Near field radiation data sampled in radiating near field and reactive near field regions are compared for far field prediction. An equivalent set of dipoles are searched by genetic algorithms to approximate the near field data, and then predict the far field. Magnetic near field peak magnitudes are obtained by a method-of-moments simulation, and far field prediction is compared with simulated data.
