Abstract

In this paper, the traditional problem of field computation for a vertical radiating antenna above a lossy infinite ground is discussed and revisited. To simplify and solve the traditional solutions consist of complicated integrals of sommerfeld type, phase stationary approximation is used. First, an infinitesimal dipole is considered over the ground and it’s attenuation versus distance from the antenna is derived. Then, to verify the results, every vertical monopole antenna is supposed to be made of the large number of the infinitesimal dipoles and so it’s charactristics such as pattern can be easily calculated. Agreement between our results and previous ones shows acceptable accuracy of this method. This method is valid for any vertical arbitrary source alignment or observation position.
