Abstract
An antenna system, an apparatus, and a method for configuring an antenna system are provided. The antenna system includes a dielectric substrate. The dielectric substrate has a top surface and a bottom surface. The antenna system also includes a first planar inverted-F antenna (PIFA) radiating element and a second PIFA radiating element disposed on the top surface of the dielectric substrate, each of the PIFA radiating elements having a F-head portion. The antenna system also includes at least two defected ground structures (DGSs) disposed on the bottom surface of the dielectric substrate and configured to provide isolation between the first and the second PIFA radiating element. Each DGS includes a varactor diode. The antenna system also includes a bias circuit corresponding to each of the at least two DGSs.
