| الملخص: | A flat antenna is proposed for the Direct Broadcast Satellite (DBS) reception. The flat antenna which is high efficiency and high gain planar antenna comprises many small antenna elements in its surface. Radial Line Slot Array (RLSA) antenna is one kind of the flat antenna which is another alternative feature that can be use to replace the conventional parabolic antenna. This project involves the study of the characteristics effects of the flat (RLSA) antenna by developing the test-bed for calibration between the DBS receiver and the flat (RLSA) antenna for Direct Broadcasting Satellite (DBS) application in Ku band frequency. In order to evaluate the performance of RLSA antenna in the setup, one of the conventional components e.g. using offset parabolic antenna, that is provided by ASTRO broadcasting company and another one is replace the offset antenna with RLSA antenna test-bed respectively. The performance result had been compared which is given by the manufacturer to show that the RLSA antenna is comparable to the commercially offset parabolic antenna. |
