Investigation on Effect of Height over an Antenna Performance
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2014, Vol 3, Issue 6
Abstract
The antenna is the most essential element in every communication system. Radiation pattern is the most important specification to be considered while designing an antenna. It is evident that the shape of the radiation pattern depends on spacing between the elements, types of the elements, number of element in any array, current distribution and phase distribution. Along with the above factors the radiation pattern also depends on the height of an antenna from the real ground. Due to this fact in the present work, some investigations are made on the influences of the real ground on the current distribution given to an antenna. Results are taken at the height h=1.5m above the real ground plane. Sommerfeld method is used for the evaluation of modified current distribution. The results are presented for influence of the real ground on the radiation pattern in both perfect electric conductor (PEC) and perfect magnetic field conductor (PMC). The results are obtained using WIPL-D program.
