Abstract
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 (S11≤−10dB) of 3.18GHz (from 3.32–6.50GHz) and the peak gain throughout the frequency band is 4.5dB. 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 S11≤−10dB is 2.44–2.58GHz and 3.5–8.85GHz which cover all the WLAN (2.4/5.2/5.8GHz) bands, WiMAX (2.5/3.5/5.5GHz) bands and point to point (5.925–8.5GHz) 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.
