Compact Slotted Planar Inverted-F Antenna: Design Principle and Preliminary Results
A new slot configuration for a compact Planar Inverted-F Antenna is presented. The proposed configuration enables a size reduction up to 25%, in comparison with the classical PIFA design. A parametric analysis of the design parameters is presented to explain the behavior of slotted PIFA, and a T-shaped ground plane technique is adopted to enhance the operation bandwidth in the ISM-band (2.4 – 2.5 GHz), thus being useful for wearable applications.
