Antena de microfita sobre substrato de ferrita de cobalto

Abstract

The research regarding to this paper is about the fabrication of a microstrip antenna with substrate of  a magnetic material: the cobalt ferrite, that was made using the sol-gel technique. The antenna was simulated via the software Ansoft HFFS® for an initial visualization. Posteriorly the antenna was fabricated, and its parameters was measured. The results was shown that the cobalt ferrite substrate miniaturizes the constructed antenna, enhancing also temperature and mechanical resistance, maintaining the radiation pattern expected for a non-magnetic substrate (for the relative magnetic permeability of 1,10).
