In this paper, implementation of Uniaxial Perfectly Matched Layer (UPML) boundary condition to efficiently analyse ultra-wide band (UWB) printed monopole antennas (PMA) using the three dimensional Finite Difference Time Domain (3D - FDTD) method are presented. A new design of UWB PMA is used for 3D UPML - FDTD implementation. The obtained solutions are compared with the results acquired from Ansoft HFSS software.

Small sized Co1-xNixFe2O4 ferrite particles are synthesized by chemical route. The precursor materials are annealed at 400, 600 and 800 C. The crystallographic structure and phases of the samples are characterized by X-ray diffraction (XRD). The annealed ferrite samples crystallized into cubic spinel structure. Transmission Electron Microscopy (TEM) micrographs show that the average particle size of the samples are <20

In the present investigation, the dielectric property of a new composite material is studied using the grounded coplanar waveguide (GCPWG) technique over a broad frequency range at X-band microwave frequencies for its application as a substrate material in microwave passive devices. The substrate material is fabricated by reinforcing NiFe2O4 particles in different volume fractions into low density polyethylene (LDPE) matrix.
