Site Attenuation for Various Ground Conditions
Summary :
Site attenuation (CSA) is investigated theoretically and experimentally for soil ground test sites as well as for metal ground test sites. In this study, half-wave tuned dipole antennas are used in the arrangements specified in ANSI standard. The CSA is evaluated numerically by introducing effective reflection coefficients, which yield an excellent agreement between theoretical and experimental results. It is found that, for horizontal polarization, differences in the CSA values between soil ground test sites and metal ground test sites decrease with increase in antenna separation distance. The deviation may reach about 4 dB for a separation of 3 m. On the contrary, in the case of vertical polarization, the CSA values of soil ground test sites deviate more than 6 dB from those of metal ground test sites at longer separation distances, such as 10 m or 30 m. In addition, theoretical investigations were made on effects of dimensions and terminations of the dipole antennas used in site attenuation measurements.
