Novel dual-band planar inverted-F antenna

The development of small integrated antennas plays a significant role in the progress of rapidly expanding wireless communication applications. This paper describes a novel planar dual-band inverted-F antenna (PIFA) for wireless local area network applications. The proposed PIFA uses single feed only. Two top plate geometries, a conventional L-shaped and a novel U-shaped slot, has been compared and discussed. A dual-band example is given for the both slot shapes for frequency bands of 2.4 GHz and 5.2 GHz. Simulation based upon method of moments (MoM) is used to model the performance of the antennas. Comparisons with measured results on fabricated antenna structures are provided for simulations validation.
