Investigation of dipole antenna radiation pattern over planar lossy half-space

Monopole and dipole antennas have been commonly used especially in wireless communications. Therefore, the electrical properties of these types of antennas on their location affect the antenna radiation pattern which is important for efficiency of the communication system. In this study, for different electrical properties with ground planes -very dry, dry, wet and ice- on which a half wave dipole antenna´s radiation pattern how changed was analysed by utilizing from the method of moments solution of Hallen´s integral equation and image theory with reflection coefficient approximation.
