Radio blockage by local obstacles such as fences, building parapets and buildings is a problem common to mobile radio and cellular telephone systems in high density urban areas. Plane wave incidence is an approximation which simplifies analysis of the scattering problem, but this is not an accurate assumptions if the obstacle is near the antenna. It is shown that an array of complex point sources is a powerful technique for calculating the effects of local obstacles on antenna patterns
