New slot configurations for dual-band planar inverted-F antenna

This paper describes a novel planar dual‐band 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, an L‐shaped and a novel U‐shaped slot, are discussed. An example for both slot shapes is given fo...

Description
Summary:This paper describes a novel planar dual‐band 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, an L‐shaped and a novel U‐shaped slot, are discussed. An example for both slot shapes is given for frequency bands of 2.4 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 simulation validation. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 28: 293–298, 2001.
