Abstract
In this article, a novel design of a planar antenna with modified patch and defective ground plane for UWB applications is presented. The optimum dimension of the antenna is 20 × 25 × 1.5 mm 3 and it is fabricated on commercially available low-cost FR-4 substrate having relative permittivity (ε r = 4.3) and relative permeability (μ r = 1) with a loss tangent of 0.025. The impedance bandwidth of the proposed antenna (magnitude of S11 [S11 < −10 dB]) is 110% (3.1-10.8 GHz). The peak gain and the peak radiation efficiency of the proposed antenna is 5.1 dB and 89%, respectively, in the proposed band of operation. Simulated and measured results of the proposed antenna are in good agreement. The proposed antenna is suitable for ultra-wideband applications, 3.5/5.5 GHz WiMAX band, 5.2/5.8 GHz WLAN band, 4/6 GHz satellite communication, and various other wireless communication applications.
