Acoplamento de Modos Guiados em Sistemas TDSL Utilizando Antenas com Simetria Radial


Recently, the exploitation of twisted pairs used as waveguide, as an alternative to the transmission lines mode, has gained prominence, mainly in order to reach the high demands of data. One of the challenges for this implementation is the coupling of the guided modes in the twisted pair, in this context, this paper aims to investigate the coupling of signals in these structures using antennas with radial propagation. The results were obtained by numerical simulations, in terms of the antenna scattering parameter and the electric field strength in the pair, demonstrating a coupling efficiency of 27.12% in 0,3 THz.
