The effects of different dispersive material fillings on the input return loss of a planar inverted‐F antenna (PIFA) are explored. In particular, we consider magnetic fillings, which allow the resonant frequency of the PIFA to be reduced while approximately maintaining the relative bandwidth. Uniaxially anisotropic magnetic fillings are also investigated and interesting features are revealed. A PIFA with an infinite ground plane is numerically studied using finite‐difference time‐domain (FDTD) method. © 2005 Wiley Periodicals, Inc.
