A new compact, multiband, single-feed planar inverted-F antenna (PIFA) for laptop computers is presented. The proposed largebandwidth radiating system is designed to operate in the IEEE 802.11a (5.725–5.825 GHz), IEEE 802.11b (2.4 –2.48 GHz), and HIPERLAN2 (5.470 –5.725 GHz) frequency bands. The overall size of the antenna and its dimensions are suitable for its installation in any position along the border of the display of a laptop computer. The design procedure is illustrated and discussed. The antenna behavior has been analyzed by resorting to both a conformal finite-difference time-domain (CFDTD) simulation procedure and a finite-element method (FEM) based technique. The simulation results are shown for the antenna in free space as well as when it is mounted in the border of a notebook display. A prototype is realized and the measurement results show good agreement with the simulation data

Abstract
A new compact, multiband, single-feed planar inverted-F antenna (PIFA) for laptop computers is presented. The proposed largebandwidth radiating system is designed to operate in the IEEE 802.11a (5.725–5.825 GHz), IEEE 802.11b (2.4 –2.48 GHz), and HIPERLAN2 (5.470 –5.725 GHz) frequency bands. The overall size of the antenna and its dimensions are suitable for its installation in any position along the border of the display of a laptop computer. The design procedure is illustrated and discussed. The antenna behavior has been analyzed by resorting to both a conformal finite-difference time-domain (CFDTD) simulation procedure and a finite-element method (FEM) based technique. The simulation results are shown for the antenna in free space as well as when it is mounted in the border of a notebook display. A prototype is realized and the measurement results show good agreement with the simulation dataI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
