Table 3 shows the optimization of the designs and
comparisons were made in order to choose the best design.
Since, the desired design is the array configuration, thus the
simulations for single antenna were not very extensive. The
single patch antenna design is needed for performance
comparison with the patch array antenna. Thus, the extent of
effectiveness of array configuration can be observed when
comparing both types of configuration. Besides that, it will
be necessary to vary the patch width, length and other
parameter such as length of microstrip line of 100 Ω in
order to optimize the performance of antenna. As the result,
the best design for single patch antenna is highlighted in
blue row and the yellow-in-colour highlighted row is chose
to be the best design of the microstrip rectangular patch
array antenna. After all this calculation and consideration
has been taken into account, both antennas were simulated
using CST Microwave software. However, only the patch
array antenna was fabricated as in fig.3. The size of the
fabricated antenna is 234mm x 150mm.
