Híbrido rat-race miniaturizado para la banda ISM 2,4 GHZ

Abstract

This paper presents the design, implementation and evaluation of a miniaturized Rat-race hybrid implemented in substrate CER-60 with microstrip transmission lines in a novel space-filling curve. This circuit is the main research's result of the project PS 3206funded by the Pontificia Universidad Javeriana. The hybrid achieves a miniaturization of 73 %, it operates in the 2.4 GHz ISM band, with an optimum operating frequency 2.56 GHz and a fractional band width of17.15%.
