Abstract :
The rapid developments in the wireless communications industry demand novel antenna designs that can be used in more than one frequency band. Applications include: dual-band cellular phones; laptop computers for wireless printer and modem connections; laptops in wireless local area network (LAN) applications; Bluetooth devices. Ali, M. et al., (see 1998 IEEE Antennas Propagat. Soc. Int. Symp. Dig., p.794-7, 1998) describe a dual-band strip-sleeve monopole antenna for use on a laptop computer. We extend the antenna design to be used for dual-band ISM applications. In this application there is a particular interest in obtaining an increased operational bandwidth for the antenna. The effects of design parameters of the microstrip-fed uniplanar monopole antenna on its operational frequency and impedance bandwidth are presented and discussed. The antenna resonates at 1800 MHz and 2450 MHz.
