A Compact Dual-Band Fork-Shaped Monopole Antenna for Bluetooth and UWB Applications (original) (raw)

A simple, low-cost, and compact printed dual-band fork-shaped monopole antenna for Bluetooth and ultrawideband (UWB) applications is proposed. Dual-band operation covering 2.4-2.484 GHz (Bluetooth) and 3.1-10.6 GHz (UWB) frequency bands are obtained by using a fork-shaped radiating patch and a rectangular ground patch. The proposed antenna is fed by a 50-microstrip line and fabricated on a low-cost FR4 substrate having dimensions 42 (sub) 24 (sub) 1.6 () mm 3. The antenna structure is fabricated and tested. Measured 11 is 10 dB over 2.3-2.5 and 3.1-12 GHz. The antenna shows acceptable gain flatness with nearly omnidirectional radiation patterns over both Bluetooth and UWB bands.
