Diseño e implementación de una antena compacta de tres bandas uniplanar para relojes inteligentes portátiles.

Abstract

The objective of this degree work was to design a compact uniplanar three-band antenna, which can be implemented in portable smart watches (smartwatch). For this, the theory of antennas was analyzed, as well as the design and management of the Ansys HFSS software, Initially the sketch parameters were established as operating frequencies (2,4 GHz-3,8 GHz5,8 GHz) and materials for its construction (FR4 Substrate), Next, the schematization and calculation of dimensions of a 2,4GHz monopole was carried out, as well as a patch that will act as a ground plane, which were recreated in the Ansys HFFS software to modify its shape and dimensions until obtaining the parameters of proposed design. A multiband antenna with measurements not greater than 38x38mm was obtained. For its implementation, the thermal transfer method and the use of CNC machinery were used, where several prototypes were made for the respective tests. These tests were carried out using the KEYSIGHT E5071C network analyzer to observe the reflection coefficient and the Curricular Integration work of Mr. Emilio Ruiz which facilitates obtaining the radiation pattern. Finally, the respective comparisons between simulation and implementation of the multiband antenna were made, determining the parameters and factors that differentiate one from the other.
