Array antennas offer a wide range of opportunities in the variation of their
directivity patterns through amplitude and phase control. Directivity is one of very
important parameters when optimizing Antenna. This paper intends to investigate
the effects of different geometries of array antenna on directivity and side lobe levels.
A six by four antenna array was chosen for investigation with uniform element
spacing between the elements and the results were presented for each selected
geometry, Array elements of dipole and patch antenna were chosen for the investigation
and analysis. An analysis of the effect of the chosen antenna array was done
by investigating its response when an incident emw (electromagnetic waves) from a
mobile phone impinge on the array antenna where the tapering and beam-forming
techniques were used for analysis and results presented.
