Patch Antenna with Electrically Tunable Ferrite-ferroelectric Bilayer

摘要：

　　A coaxial-fed patch antenna with a ferrite-ferroelectric bilayer above a regular alumina substrate has been designed and analyzed.The ferrite-ferroelectric bilayer,multiferroic heterostructure,consists of a near-single-crystal ferrite yttrium iron garnet(YIG)film layer and a ferroelectric ceramic barium strontium titanate(BST)film layer with thicknesses of 1μm and 0.5 μm,respectively.When the electric field applied across the BST layer changes from 2.5 V/um to 15 V/um,its permittivity will be tuned,thus the operating frequency of the antenna will shift as well.We also analyze the influence of the static magnetic field variation to the operating frequency of the antenna.
