In this paper, we experimentally investigate the effect of artificial magnetic material loading on the radiation properties of a planar inverted F‐antenna (PIFA). We introduce two principal strategies for the utilization of the magnetic material with planar antennas. It is shown that a dramatic bandwidth enhancement is achievable when the material is utilized in its resonant regime. In addition, it is experimentally proven that at frequencies below the material resonance, the load can be considered as a paramagnetic material, thus enabling efficient size miniaturization. © 2005 Wiley Periodicals, Inc.
