چکیده

Two novel compact antennas for covering the GSM900, GSM1800, WLAN (2400MHz to 2484MHz), Bluetooth (2402MHz to 2483.5MHz) and ISM (2450MHz) bands are presented. Two structures called Folded Inverted Conformal Antenna (FICA). The proposed antennas consist of a C-shaped elongated flat conductor featuring a closed slot, the ground plane, the shorting wall, the shorting pin and the probe-feed. The foam substrate applied in both antennas is cheaper and better than other substrates. One antenna designed for resonance in 900MHz, 1800MHz, and the other antenna has a wide impedance bandwidth measured at about 1.85GHz (2.38GHz to 4.23GHz) with low VSWR level and good radiation characteristics. The simulated values of the 1g and 10g local and averaged peak SAR on human head and hand caused by the dual band FICA mounted on handset were analysed and discussed. In both antennas good agreement is achieved between measurement and simulation
