In this paper, a new microstrip monopole compact antenna is designed by using two fractal structures: Giuseppe Peano and Sierpinski carpet for ultra-wideband (UWB) applications and satellite communications. It consists of a square patch with two steps, and a rectangular slot on the partial ground plane. The antenna is simulated using a microstrip feed line and an FR-4 dielectric substrate with ԑr = 4.3 and tanδ = 0.025. The first iteration of the Giuseppe Peano and two-level iterations of Sierpinski carpet fractals have been applied on the patch. The simulated results conducted by the CST Microwave Studio Simulator show reasonable agreement with the measured results. The frequency range obtained for S11 < – 10 dB is 3.1-12.2 GHz, relatively 118.95 % with a bandwidth enhancement of approximately 63.51 % compared to the basic antenna. The stated antenna is also compared with the related literature reviews to differentiate its performance. The designed antenna exhibits omnidirectional radiation patterns and a good gain over the entire band with a peak of 5.2 dB at 12 GHz. The proposed antenna shows satisfactory radiation efficiency, compact size, and easiness to manufacture which makes it a strong candidate for practical UWB applications and satellite communications.
