A Planar CPW Fed Antenna with Modified Ground for UWB

Ansal K A

Abstract


In this paper a U-Shaped Coplanar waveguide fed antenna with modified ground plane structure for WIMAX and WLAN applications is presented. The antenna is resonating at different frequencies 3.55/8.2/10 GHz which is cover 3.1GHz to 10.6 GHz Ultra Wide Band range.Antenna has simple planer structure of 23x16x1.6 mm3 using FR4 epoxy substrate dielectric constant 4.4 and loss tangent of 0.002 with a slot on ground plane. The proposed antenna achieved return loss -10 dB and it reached around -37 dB which covers the bandwidth specification of WIMAX and WLAN. The antenna is simulated using simulation tool Mentor GraphicsIE3D electromagnetic solver which is based on method of moment.
