Far field estimation on earth from near field measurements for car windscreen based antenna

In this paper, we propose a method for estimating the far field of an automotive windscreen antenna using near field information from an arbitrary antenna (Black Box model). Real wave source information is derived based on method of moments (MoM) by linear approximation of conductor surface, and far field estimation is performed assuming the mirror image source relative to earth using plane wave reflection coefficient. The effectiveness of the proposed method is demonstrated by using an antenna on a glass window (windscreen) as the estimation target of a simple car model.
