Design of Compact UWB Printed Slot Antenna for GPS, GSM &Bluetooth Applications .

The proposed design consists of an octagonal-shaped slot fed by a bevelled and square patch for covering UWB band (3.1–10.6 GHz)with extra the GPS (1.52-1.58GHz),GSM(1770–1840 MHz) & Bluetooth (2.3-2.48GHz) bands. Radiation patterns are stable and bidirectional with 6.5989 DB gain throughout the band. Radiation efficiency is 97.12%. Extensive simulation results using HFSS simulation software.
