Abstract-A dual-band bow-tie-shaped CPW-fed slot antenna design for wireless communication applications is proposed. The antenna consists of a signal strip, two conducting strips and bow-tieshaped slots. With simple tuning geometrical parameters, the proposed antenna is suitable for WLAN 2.4/5.2/5.8 GHz bands. This antenna is designed on a single-layer PCB FR4 substrate with permittivity εr = 4.4, loss tangent tan δ = 0.0245 and thickness h = 1.6 mm. The antenna size of the radiating area and ground plane is 60 × 45 mm 2 . The measured results show a positive agreement with the simulated results.
