Using the CADFEKO tool, a T-shaped Microstrip patch antenna (MSPA) with an epoxy substrate was designed and simulated to achieve the best possible result. MSPA is frequently utilized because of its numerous benefits, including its light weight, low volume, and low manufacturing cost. The antenna's bandwidth, gain, return loss, VSWR, and radiation pattern were assessed. Maximum impedance is attained at 6.85 GHz, antenna gain is 8dB, directivity is 4.5, and return loss is -10.80dB at 5.725 GHz and 12.48dB at 10.6 GHz for the T-shape rectangular Microstrip patch antenna for ultra-wideband applications. 50Ω is used to power the T-shaped Microstrip antenna. The simulated results of the proposed antenna are good radiation patterns. The return loss is less than -10 dB and VSWR is less than 2 throughout the UWB band. At 3.1 to 10.6 GHz resonant frequencies, the S11are -10.80dB,-12.48dB, and antenna efficiency is 100 % due to all losses being zero.
