Técnicas para mejorar el ancho de banda en antenas tipo parche : Antena tipo parche con perturbaciones en su estructura para mejorar el ancho de banda.

Abstract

Current communications systems have the need to transmit a greater amount of information and a higher speed, this entails transmissions at very high frequencies as is the case with 5G; which in turn means more bandwidth. Patch antennas, being of very low manufacturing cost and being integrable with microwave circuits, are being widely used; however, these antennas have certain drawbacks, among which is their narrow bandwidth. This work contains 3 chapters, the first chapter covers the characteristics, design processes and techniques to improve the bandwidth of patch antennas, in the second chapter modifications are made to the base model through the use of slots and bevels to introduce a new contiguous resonance and increase the bandwidth, in the third chapter with the help of the electromagnetic simulation software the results are presented with the techniques described above, to finally analyze other important parameters of the antenna such as polarization or gain.
