This research investigates how the number of elements affects the monopole antenna's planar array's directivity. This study also takes into account the antenna's effect on the whole field it radiates. The monopole antennas are arranged in a planar configuration with all the components in their proper locations using the Hadamard matrix approach. Each matrix's directivities and array factors were calculated, and a MATLAB tool was used to simulate the radiation pattern. A range of elements from 4 X 4 to 50 X 50 planar layouts were taken into consideration during the investigation. Increasing the number of elements improves the directivity. Increasing the number of elements in the planar array resulted in a great improvement in directivity, as seen by the computed and simulated results. Consequently, by increasing the antenna's directivity, a greater number of elements influences the overall field emitted.
