Triple band planar inverted F antennas for handhelddevices

Abstract

Two novel triple band planar inverted F antennas (PIFAs) are presented. The first antenna is realised by housing a dual frequency L-shaped spur line loaded PIFA element within the lower resonance PIFA element. The second antenna is realised by embedding two single element PIFAs within a quarter-wave patch. For both antennas, an isolation of better than –15 dB between the feed ports and a good agreement between simulation and measurement results was obtained.
