Study on bandwidth enhancement techniques of microstrip antenna
Abstract In this paper we present a Novel Triangular UWB microstrip antenna which offers an ultra wide bandwidth (UWB) greater than 8 GHz. This optimum antenna design provides satisfactory gain all over the UWB. The study includes partially truncating the ground plane (defected ground) inserting slits in the triangular radiating patch, and using different substrate materials in order to obtain band notched UWB. The simulation experiments have been carried out using the IE3D Zeland software. The final antenna design is fabricated on two substrates; FR4 and Droid 5880 (Teflon) The practical measurements well agree with the simulation results.
