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

In this paper, a microstrip line fed dual-band monopole antenna is proposed for WLAN operation with an English letter folded G-shape as radiating element. At center frequency of 2.41 and 5.49 GHz for dual band operation for WLAN applications, the proposed antenna employs an English folded G-shape radiating element that creates two paths of resonance. Two resonating paths are approximately equal to quarter wavelength length at 2.56 GHz and 5.49 GHz. The proposed antenna has the required radiation characteristics and adequate gain for operation in the WLAN band.
