| Summary: | The substrate between the patch and ground plane of microstrip antenna plays an important role in antenna design as it dictates the linear characteristics performances of the antenna. This work focusses on the comparison between three UWB antennas fabricated on different substrate materials which are Rogers Duroid RO3003™ with a dielectric
constant, εr of 3, loss tangent, tan δ of 0.010 and thickness, h of 1.52 mm; denim substrate with εr of 1.7, tan δ of 0.07 and h of 0.7 mm; and felt substrate with εr of 1.3, tan δ of 0.02 and h of 1.1 mm. From the comparison, felt substrate offers a good antenna’s performance in terms of frequency range, bandwidth, gain and efficiency followed by Rogers
Duroid RO3003™ and denim substrates. The simulation results show that the frequency range of the UWB antenna with felt substrate is from 2.31 GHz to 11.74 GHz with a bandwidth of 9.43 GHz; gain, G of 5.489 dBi; and efficiency,
