Abstract

This report describes the design and implementation of a logarithmic periodic ultra-wideband antenna from 1 to 10 GHz for the characterization of antennas; its development was carried out in the electromagnetic simulation software Ansoft Designer, taking as a starting point the mathematical calculations necessary to generate the logarithmic structure of the antenna. This type of antenna allows working with electromagnetic waves in the VHF and UHF frequency range. The antenna implementation was performed on a computer numerical control (CNC) router RUIDIAO RD-HA1325 on a sheet of dielectric substrate Roger RT/Duroid 5880. Finally, the antenna was evaluated by collecting data with measurements in the Anritsu MG3690C signal generator and the Anritsu MS2724C electromagnetic spectrum analyzer, obtaining a range of frequencies according to the proposed design.
