Abstract :
A new method of calculating 3-m site attenuation is described. To obtain an accurate site-attenuation curve, the problem of coupling between antennas is formulated in the form of coupled integral equations for the antenna currents, and solved by the method of moments (MOM). The site-attenuation curve thus obtained shows about 1.3-dB larger attenuation than that given in an IEC document. The deviations in the site-attenuation curve due to the impedance mismatch between the coaxial cable and the measuring equipment, and the influence of the antenna conductor radius on the attenuation curve are also considered. Finally, the calculated site attenuation is compared with the measured attenuation data available in the literature.
