Sierpinski carpet fractal monopole antenna for ultra-wideband applications

Microstrip antenna is broadly used in the modern communication system due to its significant features such as light weight, inexpensive, low profile, and ease of integration with radio frequency devices. The fractal shape applied geometry obtain ultra-wideband antennas. In this paper, sierpinski carpet monopole (SCFMA) developed for base case, first iteration second wideband based on space filling self-similar characteristics. dimension patch size optimized minimize overall antenna. Moreover, planar structure proposed using microstrip line feed. mounted FR4 substrate thickness 1.6 mm loss tangent 0.02 relative permittivity 4.4. performance SCFMA analyzed terms area, bandwidth, return loss, voltage standing wave ratio, radiation pattern gain. achieves three different bandwidth ranges 2.6-4.0 GHz, 2.5-4.3 GHz 2.4-4.4 respectively. compared existing antennas prove efficiency design. area 25×20 mm<sup>2</sup>, which less when
