Fig. 9 is the simulated radiation pattern of single patch
antenna with directivity of 5.898 dB and gain of 0.837. Fig.
10 is the simulated radiation pattern of patch array antenna
with directivity and gain of 10.25 dB and 5.732 dB
respectively. As both radiation patterns were compared, it
can be concluded that the array design antenna generates
more intensity or focus at the center of the radiation.
