Executive Summary

In this paper, a Planar Inverted-F Antenna (PIFA) with U-Slot (U-PIFA) and slit in ground is introduced. The proposed PIFA is compact with single coaxial feed, single short strip, and single short pin. The main achievement of this research was the design of ISM Microwave bands 2.45/5.8 GHz dual band PIFA antenna by using slit in ground to control the selection of lower resonance frequency without any mutual effect on the upper resonance frequency which determined from U-slot in the patch. The dielectric constant of the substrate is 4.3 and loss tangent of 0.013, FR-4 substrate.
