The analysis performed by this method is far more accurate for the high-gain pyramidal horns than that of approximate methods. Furthermore, this method can be used to predict the voltage standing wave ratios, aperture field distributions, and cross-polarization patterns of the antenna....
The following figure shows that the array defined above meets the requirements derived for antenna gain. Get helperPlotAntennaGain(); From the plot of antenna gain, we can see that the gain requirement is met with the given array. The array definition is referenced in the Simulink ...
