Dual-band CPW-fed hybrid antenna

A novel 2450/5600 MHz CPW-fed hybrid antenna consisting of a CPW-fed inductive slot antenna and a dual inverted-F monopole antenna is proposed and investigated experimentally. This proposed hybrid antenna exhibits dual-band behaviour with sufficient bandwidths to meet the system requirements of wireless local area network (WLAN), IEEE 802.11a (5725-5825 MHz), HIPERLAN/2 (5470-5725 MHz) and IEEE 802.11 b/g (2400-2483 MHz). Measurements show that the 10 dB return loss bandwidth (VSWR<2) for the low and high bands reaches as much as 152 MHz (2384-2536 MHz) and 350 MHz (5473-5823 MHz), respectively. Moreover, peak antenna gain is 1.62 dBi in the low band and 4.6 dBi in the high band.
