DESIGN OF A MICROSTRIP-FED MONOPOLE ANTENNA WITH A WIDE SLOT GROUND PLANE FOR UWB APPLICATIONS

In this paper, the design of a microstrip-fed monopole antenna with a wide slot ground plane for uwb
applications is presented. A wide slot ground plane is inserted in the ground plane and etched. The
substrate used is fr4 epoxy with a thickness of 1.6mm. The size of the antenna is 30*30mm, hence it’s a
compact one. The trapezoidal patch placed on the upper surface of the substrate. The radiating strip
connected to microstrip line feed tapered at one end. The simulation results shows that a return loss of less
than -10dB and a VSWR value less than 1.58 through the bandwidth 3 to 12.5 dB is obtained. The
simulation software used is high frequency structural simulator (HFSS)
