Abstract

In this study, a phased array antenna was designed using modified Least Mean Square algorithm, to adaptively track incident signals from satellite. The algorithms would form the beam perfectly and the main beam will be centered at the location of the desired signal and the nulls will be located at exactly the direction of the unwanted signals. The main beam and nulls would be steered toward incident signals automatically during adaptation process. The phased linear array using both point sources and micro-strip rectangular patch was designed. 8-elements with 0.5 wavelength separation were used. It was found that with micro-strip antenna sources placed along one of the axis, the algorithm gives a lower side lobe which gives best cancellation of interferers from other satellites with higher directivity and lower half-power beam widths.
