Single-feed dual-band planar inverted-F antenna with U-shaped slot

The development of small integrated antennas plays a significant role in th e progress of rapidly expanding wireless communication applications. This p aper describes a novel dual-band planar inverted-F antenna (PIFA) for wirel ess local area network applications. The proposed PIFA uses single feed onl y. A novel top-plate geometry, a U-shaped slot, is discussed. An example is given for this novel slot shape for frequency bands of 2.4 and 5.2 GHz. Si mulation based upon method of moments (MoM) is used to model the performanc e of the antenna. Comparisons with results measured on fabricated antenna s tructures are provided for simulations validation.
