Microstrip-line fed Dual-band C-shaped Antenna with Monopolar Characteristics for Application in WLAN

In this paper a In this paper, a dual-band planar antenna with monopolar characteristics has been proposed which is fed by a transmission line of microstrip in nature having the C-shaped element of radiation. Two paths of resonance are created in the element of radiation which is a C-shaped structure for the operation in the in the two resonance bands simultaneously at the center frequency of resonance of 2.41 GHz and 5.59 GHz for WLAN application. Two resonating paths are approximately equal to quarter wavelength length at 2.56 GHz (
$0.252\lambda_{1}$
) and 5.49 GHz (
$0.185\lambda_{2}$
). The antenna which is proposed here demonstrate the sufficient gain and pattern of radiation characteristics which which enables the antenna which is proposed suitable for application in WLAMN band of operation
