No. of bitstreams: 0 Previous issue date: 2018-01-01; Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); In this work, for the first time bacterial cellulose (BC) hydrogel membranes were used for the fabrication of antimicrobial cellulosic nanocomposites by hydrothermal deposition of Cu derivative nanoparticles (i.e. Cu(0) and CuxOy species). B...
Analysis of a reconfigurable UWB log-periodic antenna using the Method of Moments
Calmon, André du Pin; Pacheco, Guilherme; Silva, Franklin da Costa; Terada, Marco Antônio BrasilIn this article we discuss in detail the numerical implementation and computer simulations based on the Method of Moments (MoM) of the reconfigurable, ultra wideband (UWB) log-periodic antenna. The manufacturing and testing procedures are also addressed. The antenna was built utilizing low cost and/or recyclable materials and covers frequencies from 74 MHz to 2 GHz, through the discrete adjustment of its elemen...
