Abstract

In this paper, a design of compact monopole antenna with defected ground plane for wideband applications has been investigated. Initially, the partial ground plane is used which yield the impedance bandwidth (S₁₁ ≤ -10 dB) of 23.87% and 17.54% ranging (4.00 GHz-5.11 GHz) and (8.48 GHz-9.84 GHz) respectively. The bandwidth of the proposed monopole antenna is enhanced by employing the defects in the partial ground plane. Antenna is designed and simulated by using Ansoft HFSS v13 simulator; moreover, the antenna is fabricated to validate the simulated results with the measured results. Measured proposed monopole antenna with DGP (Defected Ground Plane) exhibits the impedance bandwidth (S₁₁ ≤ -10 dB) of 72.87% ranging (3.89 GHz-8.35 GHz), which covers different wireless standards such as WiMAX (3.3 GHz-3.7 GHz), WLAN (5.15 GHz-5.85 GHz), X-band satellite applications (7.1 GHz-7.76 GHz) and point to point high speed wireless communication (5.925 GHz-8.5 GHz).
