Generación de doble banda en antenas de Microcinta rectangulares utilizando ranuras separadas en secuencia de cantor

Abstract

A new microstrip antenna system is presented in this work, in which are inserted rectangular slots and different orders in the cantor sequence determine their dimension and separation. The return losses are analyzed to determine the effect of this type of slot sequence on the patch, showing the generation of dual-band behavior in the range of 1 to 6 GHz. The microstrip antenna is designed by several slots on the patch whose sizes are based on the Cantor sequence up to the fourth iteration. The presented arrangement allows having two resonance frequencies in the range of 1 to 6 GHz, the experimental results and the computer simulations show a high concordance. The simulation was performed using the HFSS software, using an FR4 substrate with er = 4.4 and a thickness of 1.58 mm. The antennas presented in this article, unlike a conventional microstrip antenna with the same dimensions, present two bands of frequency, which have slight differences between each iteration. The new microstrip antenna systems presented in this work allowed to obtain a dual-band generation after adding slots based on the Cantor sequence.
