In this paper, magneto-dielectric material is proposed to use for minimizing antenna size. One examle of very small antenna is presented to prove this with antenna's area of $0.078\lambda_0\times0.016\lambda_0$, and just moderate values of permittivity and permeability while the return loss can reach - 38 dB at the resonant frequency. The parameters of dielectric material for that best performance are $\varepsilon_r=1.71-j0.004$, and $\mu_r=2.39-j2.58$. Besides, this material also has ability to control the trade-off between the gain and bandwidth while keeping the antenna size unchanged.
