Fast Prediction of Coupling Coefficient between Monopole Antennas on Electrically Large Cylindrical Platforms Using a Linear Parametric Model
Keywords:
Antenna placement, electromagnetic interference, parametric modelAbstract
Antenna placement on electrically large cylindrical platforms requires a number of time consuming computer simulations that involve analysis of big electromagnetic data. In order to save simulation time, a linear parametric model is proposed to predict the coupling coefficient between monopole antennas on electrically large cylindrical platforms. The two parameters of the model are determined by the values of coupling coefficients at two different distances. The parametric model is then used to predict the coupling coefficient between monopole antennas at various distances. The proposed parametric model avoids repeated time consuming analysis of big electromagnetic data for predicting the coupling coefficients at various distances, and it thus significantly reduces simulation time. Given the desired level of isolation, the proposed parametric model can be used to find the required distance without a trial-and-error process, which further saves the time required by the analysis of big electromagnetic data.
