A systematic approach to quantitatively compare antenna measurements with simulations.

Abstract: The objective of this paper is to compare antenna simulations to actual measurements using a simulation software tool. This comparison is done using statistical methods in the far field region where the radiation patterns of antennas are plotted on a polar diagram. Actual antenna measurements are carried out in an anechoic chamber. The residual, correlation and sum of squares between simulated data and measured data are calculated. The theoretical directivity value of an antenna is compared to a calculated simulated directivity value. Different methods of creating a vector norm polarplot are outlined and discussed. The numerical method used by the simulation program is outlined.The results achieved will be presented and analyzed. They will also be compared to what we expected to find. The result provided high calculated values, these depend on how the simulated and measured data are matched.
