Yagi-Uda Antenna Above a Real Ground

Calculate the radiation pattern for a horizontally polarised Yagi-Uda antenna consisting of a dipole, a reflector and three directors at 400 MHz. The antenna is located 3 m above a real ground which is modelled with the Green’s function formulation.

Note: A basic optimisation setup is included with the example. Optimisation is applied to the example to determine the optimal physical dimensions, maximise the forward gain, and minimise the back lobes.
