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 peninsular and Borneo regions must be obtained. In this paper, a lightweight non-symmetrical array feed...
In the radio astronomy applications, antennas having the highest aperture efficiencies are requested. In order to meet the request, a reflector shaping program for dual reflector antennas has been developed. The conventional ray tracing method is employed in the developed program. Recently, the fourth generation programming language MATLAB is well known for its numerical computing environment and...
