The design of low-cost, wideband, Printed Inverted-F Antennas (PIFAs) that are suitable for portable devices operating at the 2 - 3 GHz band is described. The design specifications were extracted according to the constraints of high data rate wireless sensor devices. Reactive tuning through slot loading was applied to enforce degeneration of a higher resonance, and thus double the bandwidth in the band of interest. Three slotted antenna configurations are reported plus a baseline configuration; a thorough numerical characterisation of performance is provided. Fractional BandWidth (FBW) in the range 22 - 34% was achieved, which is almost quadruple that of existing implementations.
