Abstract: 

This paper describes the development of broadband patch antennas using Riemann conformal transformation, on the square in the Argand-Gauss plane for wireless local area network (2.4 GHz and 5 GHz), and 5G band in 3.5 GHz. For this work was projected three antennas with the bio-inspired shape of the elliptical leaf(MPA R1, MPA R2, and MPA R3), using Riemann conformal transformation, for an increase of the bandwidth of the narrowband antenna (square patch antenna), fractional bandwidth of 3%, to broadband antennas, with fractional bandwidth greater than 5%. The project of the antennas was generated in MATLAB, simulated in the commercial software ANSYS, and built in low-cost material, fiberglass dielectric substrate. The measured results of the bio-inspired antennas patch antennas, with Riemann transformation, operation in the 2.4 GHz, 3.5 GHz and 5.8 GHz bands, with absolute bandwidth of 135 MHz (MPA R1), 220 MHz (MPA R2) and 440 MHz (MPA R3), fractal bandwidth of 5.6% (MPA R1), 220 MHz 6.3%(MPA R2) and 440 MHz 7.6%(MPA R3), the simulated maximum gain of 6.67 dBi (MPA R1), and a half-power beamwidth of 108 degrees (MPA R2).
