The GUI for the linear and planar array is shown below. The AF input parameters, include frequency for squint calculations. There is a selection of seven weighting (tapering) functions. An isotropic radiator and four dipoles of different length can be selected for the EF. The pattern is a 1D plot of normalized power in dB versus angle. For the linear array, parameters such as half power beam width (HPBW) and squint are calculated. For the planar array, azimuth and elevation cuts at specific angles can be specified.
