Abstract

In this article, the design of a new textile antenna used for IoT applications has been presented. The proposed antenna has been designed by two resonant elements outlined over on a denim fabric material with an εr = 1.78. In order to describe the behavior, and find the optimum zone to excite the structure, the Theory of Characteristic Modes has been used. The antenna is fed by proximity in a capacitive way through two transmission lines, later the feed was transformed into a power divider that produces good impedance matching (S11 < -10 dB) from 2 GHz to 3.6 GHz with a maximum directivity around 4.84 dBi, and a stable bidirectional radiation pattern over the entire frequency range, which in the presence of the human body is transformed into unidirectional radiation pattern. Finally, the structure has been fabricated and the reflection coefficient results obtained are very similar with the simulation
