Antenna size has fundamental limits based on the frequency of operation and performance required. In the past, various methods have been developed to miniaturize antennas with limited success. Magneto-dielectric materials, however, have been reported as providing new opportunities for effective antenna size reduction in many recent studies. In this paper, a novel material characterization method which is a cavity perturbation technique (CPT) with substrate integrated waveguide (SIW) cavity resonator is presented for measuring electric and magnetic properties of magneto-dielectric material. CPT formulas for extracting complex permittivity and complex permeability are explained and modification process using 3D EM simulation tool is discussed. Design and fabrication of SIW cavity resonators is presented. The frequency dependent properties of permittivity and permeability for synthesized magneto-dielectric material are extracted in the frequency range of 1-4 GHz. Planar inverted F antenna (PIFA) working at 1GHz on magneto-dielectric substrate has been designed and simulated in this paper.
