摘要：

Microstrip patch antenna is fabricated on a magnetodielectric substrate synthesized using 5% volume fraction of nano-sized cobalt ferrite and nickel ferrite inclusions. The permittivity,epsilon(r) and permeability mu(r), of the tailored substrate is determined by in touch superstrate method and cavity perturbation respectively. The S11 parameters are measured in the frequency range from 8 to 11.5 GHz with varying external magnetic field. Unlike antennas made on bulk ferrites, the antennas on these substrates show very low resonant frequency tenability. An enhancement of return loss from -26dB to-31 dB for CoFe2O4/LDPE antenna at 9 GHz and -25dB to -32.5 dB for NiFe2O4/LDPE antenna at 10GHz is observed.
