This paper presents a novel printed monopole antenna with defective ground structure for worldwide interoperability for wireless communication. The basic design comprises of a monopole patch with co-planar ground plane which exhibits the impedance bandwidth (S-11 <= -10 dB) of 3.18 GHz (from 3.32-6.50 GHz) and the peak gain throughout the frequency band is 4.5 dB. The initial design is further modified to enhance the impedance bandwidth and gain by employing a defective ground structure in the co-planar ground plane of the monopole patch. The measured bandwidth for return loss S-11 <= -10 dB is 244-2.58 GHz and 3.5-8.85 GHz which cover all the WLAN (2.4/5.2/5.8 GHz) bands, WiMAX (2.5/3.5/5.5 GHz) bands and point to point (5.925-8.5 GHz) high speed wireless applications as per ECC and FCC frequency standards. The experimental and simulated results of a novel CPW-fed (co-planar waveguide) printed monopole antenna with DGS (defective ground structure) are reported here.
