Performance of the antenna is crucial for wireless applications. It has the ability to send and receive electromagnetic radiation. When wireless antennas come into contact with the signals, their electromagnetic waves will bounce off of them. Numerous studies recommend an antenna that can generate multiple frequencies running in the 1 GHz to 10 GHz range, including the operating range of C-band and S-band applications. S11 < − 10 dB return loss is the specification for the antenna. The design of the antenna makes use of a rectangular microstrip patch and a fractal Sierpinski carpet technique. The parameters used in the actual antenna design and executed for a third iteration are 0.06 mm for the thickness and εr = 4.4 for the relative permittivity of the Epoxy FR-4 substrate. According to the test results, the third iteration of the Fractal carpet antenna can operate at four different frequencies: 3.5, 4.9, 7.2, and 8.6 GHz. Gain plots demonstrate that the built antenna satisfies the requirements to be used in a wide range of wireless applications.
