Monopole Antenna on a Finite Ground Plane

Calculate the radiation pattern for a wire monopole antenna on a finite ground plane. The ground plane is modelled as a circular PEC ground plane.

The circumference of the circular ground is 3 wavelengths at 75 MHz. The wire radius of the monopole antenna is 1 mm.
