Abstract
A printed dipole antenna with two U-shape dipole arms for multiple wireless services is presented. Prototype of the proposed antenna has been constructed and tested. The impedance characteristic is studied as a function of antenna dimensions. The proposed dipole antennas are shown to yield impedance bandwidth ratios of >90% for VSWR=2:1, which simultaneously supports multiple wireless services, such as PCS (Personal Communication Service), IMT-2000 (International Mobile Telecommunication-2000), and 2.4 G WLAN band.
