A study on configurations of magnetic material loaded Planar Inverted-F Antenna using topology optimization

In this paper, the effects of μ
r
and tanδ on the magnetic material loading amount for the miniaturization of the PIFA have been presented using topology optimization technique. As μ
r
increases, the magnetic material loading amount for the PIFA was decreased. And, the configurations of loading materials were cleared. In addition, it was confirmed that the effect of dielectric loss of the magnetic material depends on the condition of μ
r
.
