Abstract
This work presents the analysis of monopole microstrip antennas with truncated ground plane and patch geometry inspired on the Mandelbrot fractal curve for applications in UWB systems. The proposed antenna geometry is analyzed using the Wave Concept Iterative Procedure (WCIP), a full-wave method. Results for the proposed antenna operating frequency, bandwidth, VSWR, gain, and radiation pattern are obtained and discussed. The WCIP results are compared with simulation results provided by HFSS software, for validation purpose. In addition, a prototype antenna is built and measured. A good match between WCIP theoretical and simulation, HFSS simulation, and measurement results is observed for the antenna frequency response.

Summary
The continuous advance in wireless communication systems has motivated many researchers worldwide to investigate and develop antennas for ultrawideband (UWB) system applications. This paper describes the analysis of a monopole microstrip antenna printed on textile substrate for applications in UWB systems. Several authors have studied the application of fractal geometry in the design of planar antennas and printed antennas for UWB applications [16,17,18]. In [16], a low-profile compact CPW-fed fractal patch antenna based on a slotted circular shape was proposed for UWB applications. A monopole antenna comprising a fractal radiating patch with folded T-shaped element was designed to operate over the entire UWB frequency range [17]. A. International Journal of Antennas and Propagation miniaturized UWB monopole antenna designed by the combination of two fractal geometries was proposed in [18]. Good agreement has been observed between the results obtained by WCIP formulation, HFSS simulations, and experiments
