Abstract
The paper presents the synthesis, characterization of Lanthanum substituted Barium ferrite material and its real time application in the development of miniaturised navigational antenna at 2.492 GHz. The Lanthanum substitution is observed to increase the ferro magnetic resonance frequency of BaFe12O19 parent material because of its octahedral site preference. Among the synthesized material, the BaLa0.2Fe11.8O19 material has resulted in higher effective magnetic permeability of around 2.5 and dielectric permittivity of around 5.5. The Quadrifilar helix antenna which is miniaturised by loading the BaLa0.2Fe11.8O19 material has the axial height reduction of 59% compared to the conventional quadrifilar helix antenna, while retaining the radiation characteristics like gain and band width.
