Hi, I was wondering if anyone knew how to calculate the HPBW (Half Power Beam Width) of a half wavelength, one wavelength, and 3/2 wavelength dipole? Or is there any code for this that can be done. I understand that theoretically a half wavelength dipole should be about 78 degrees, but how would I prove it with calculations using Matlab? Thanks!
