Abstract :
An efficient physical optics based method of analysis of antennas over finite ground planes is presented. The far field radiated by the current on the finite ground plane is expressed as the convolution integral of the far field of the antenna above the infinite ground plane with the Fourier transform of the polygonal ground plane shape. The convolution integral is simplified by applying the sampling theorem
