This work presents the design and simulation of Rectangular Microstrip Patch Antennas (MPAs).
The Conventional Rectangular MPA using copper as conductive patch and FR-4 as substrate material is
design. The simulated results obtained from the design of conventional (MPA) shows that, the antenna
resonate at 10.2 GHz with a return loss (S11) of (-19.364dB). Due to low bandwidth of the conventional
design, the two additional antennas was design with rectangular slot and circular slot on the patch antenna. In
which the result obtained shows that, the antenna with rectangular slot resonated at 10.16GHz GHz with a
return loss (S11) of (-20.53dB). And the MPA with circular slot resonated at 10.198GHz GHz with a return
loss (S11) of (-22.03dB). This result shows that, the proposed antenna with rectangular slot has higher
bandwidth than the conventional MPA and that of MPA with circular slot.
