• The magneto dielectric material (MDM) is proposed to use for minimizing antenna size in this paper. Two examples of meander line and patch antenna are presented to prove the ability of miniaturization by use of the MDM and the cylindrical magneto material (CMM), respectively. The first proposed antenna, whose size is very small with overall dimension of 0.078λ_0×0.O16λ_0×0.0023λ_0, has return loss, and bandwidth of-38dB, and 58MHz at 433.92MHz, respectively.. The parameters of dielectric material for that best performance are ε_r=1.71-j0.004, and μ_r=2.39-j2.58. The second example of patch antenna with feeding line structure sealed by the CMM shows high gain pattern and broad bandwidth with comparison of antenna with magnetic material substrate.
