SUMMARY:

The continuous development of communication circuits has enabled to overcome several previously established difficulties. MIMO antennas, for example, have significant advantages over simpler antenna configurations, since the redundancy of the signal sent and received enables to reduce errors and increase the data transmission rate and the channel transmission capacity. However, printed antenna geometries usually present isolation problems between the elements of the circuit, generating some anomalies for the desired operation. Therefore, as the complexity of these circuits increases, with the objective of improving performance and minimizing size, the integrated use of isolators is recommended. In addition, printed antennas have also expanded their purposes. In addition to enabling communication between devices for data exchange, they are currently used as sensors to: evaluate or detect essential parameters in various applications in civil construction, such as vibrations and cracks, in medicine, as in cancer treatment, and in radar systems to report on the proximity of icebergs, the location of aircraft and even the occurrence of rain. This work proposes an exclusive design technique for the sensing of several parameters, with applications in several areas (civil engineering, materials engineering and biomedical engineering, for example) through the interpolation of data from samples of different materials, with known parameters. In addition to applications in the development of low-cost radar systems, to accurately locate the direction of specific RF sources, and of broadband isolators inspired by the Cantor fractal for optimization of MIMO antenna designs.
