Composite of Flake-Shape Sendust Particles and its Application on Patch Antenna

Abstract:

Flake-shape Sendust particles with high microwave magnetic permeability and permittivity were prepared with the method of wet ball milling, and then mixed with the polymer to get a sheet-type composite as an effective EMW absorber. It was found that the composite has a very high shape factor owing to the flaky Sendust particles, which can break through the traditional Snoeks limit, and achieve a high effective magnetic permeability. HFSS simulation results show the sheet-type composite can be used on the patch antenna for improving the front-to-back ratio of the hand-held patch antenna and reducing the EMW pollution around antenna operators.
