A novel CPW-fed wideband printed monopole antenna with DGS
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 3.326.50GHz) 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 2.442.58GHz and 3.58.85GHz which cover all the WLAN (2.4/5.2/5.8GHz) bands, WiMAX (2.5/3.5/5.5GHz) bands and point to point (5.9258.5GHz) 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.
