Abstract

A folded inverted F antenna (FIFA) (20) includes an L-shaped receiving element (30) having a first planar portion (34) and a second planar portion (36) connected along a fold edge (38). A printed circuit board (PCB) (40) is disposed perpendicular to the second planar portion (36) forming a PCB ground plane. The FIFA includes a second ground plane (42) disposed below and arranged approximately in parallel with the second planar portion (36). At least one shorting conductor (54) couples the receiving element (30) to at least one of the PCB and second ground planes (40, 42). At least one receive conductor (58) couples a receiver circuit (50) to the receiving element. The FIFA is adapted for use in a wireless communication device, such as a cellular phone, for receiving position signals from a global positioning system (GPS) satellite. The FIFA exhibits an enhanced sensitivity field to electric and magnetic fields traveling along a zenith direction and greater antenna gain than conventional planar inverted F antennas (PIFA).
