Design and analysis of a satellite-mount array-fed parabolic antenna by electromagnetic computations

Precise contoured beam is very important in designing antenna system for satellite broadcasting application. Through accurate contoured beam design, constant signal and optimum beam performance can be achieved throughout the region. For the case of Malaysia, two separate contoured beams for the peni...
