The Gaussian Antenna Model uses an ytical model of a Gaussian = beam. This antenna pattern is similar to the pencil=20 beam pattern. Consider representing the main beam of the antenna pattern using a Gaussian. Let’s also define beam efficiency: We know the integral of a Gaussian function, Ultra Gaussian Horns; ESR Systems; ESR Systems for AB VNAs; This advance is more important than just a nice antenna pattern: In particular,
