Abstract :
This paper describes a novel dual-band planar inverted-F antenna (PIFA) for which the impedance bandwidth can be remarkably improved. The proposed PIFA uses a single feed only. Two top plate geometries, a U-shaped and a novel meanderline-shaped slot, are discussed. An example is given for frequency bands of 2.4 GHz and 5.2 GHz. Simulation based upon the method of moments is used to model the performance of the antennas. Comparisons with measured results on fabricated antenna structures are provided for simulations validation.
