For satellite communication, precise Malaysia coverage is requesting. In this paper, multi beam coverage is studied. In order to arrange multi beams at exact positions, exact feed position are determined through focal region ray tracings. Then, a multi beam reflector antenna is designed and beam allocations are examined. Adequateness of feed position(More)
This paper presents the design of a 1×4 microstrip array antenna operating at 6.3GHz for C-band communication satellite application. The project aims to investigate the ability of the array to control the direction of the main lobe through a systematic least mean square method and to validate the design through accurate electromagnetic analysis. The(More)
This paper proposes radiation reconfigurable patch antenna using feeding delay line technique. By using simulation and optimization from Computer Simulation Technology (CST) the 2 × 2 antenna array is designed and investigated. The direction of radiation pattern is controlled by interchanging two different lengths of corporate feeding network using(More)
When covering Malaysia area by multi beams in satellite antenna, many feed horns are employed. In a previous designing, severe horn overlapping was shown. In this paper, overlapping problem of feed horn is analytically studied. The relation of feed horn size and feed position displacement is numerically clarified with parameter of the beam separation angle(More)
Reflector antennas remain the most preferred option for satellite communication. However, some applications require the beam to be shaped precisely to the specific coverage region in order to provide high data rate services with constant signal availability. As for small region like Malaysia, it is very crucial to obtain precise beam shaping because it is(More)
