摘要: A simple, low-cost, and compact printed dual-band fork-shaped monopole antenna for Bluetooth ultrawideband (UWB) applications is proposed. Dual-band operation covering 2.4-2.484 GHz (Bluetooth) 3.1-10.6 frequency bands are obtained by using a radiating patch rectangular ground patch. The proposed fed 50-Ω microstrip line fabricated on low-cost FR4 substrate having dimensions 42 (Lsub) × 24 (Wsub) 1.6 (H) mm3. structure tested. Measured S11 ≤ -10 dB over 2.3-2.5 3.1-12 GHz. shows acceptable gain flatness with nearly omnidirectional radiation patterns both UWB bands.
