A compact size ultra-wideband (UWB) microstrip antenna with improved performance is proposed in this communication. In this article, the design of the antenna, which is based on the interaction between the circular patch and the rectangular slot cutting in the metal ground plane, as a result the required starting frequency can be achieved due the coupling between the metal ground plane and patch. UWB microstrip antenna is studied and designed using computer simulation. For verification of simulation results, the antenna is fabricated and measured. The simulation and measured results as reflection coefficient and radiation pattern are presented. Its measured results indicate that the proposed antennas achieve UWB from 1.49 GHz up to 18 GHz with improved the radiation pattern performance in the upper frequency range(up to 10 GHz). Proposed antenna achieve many wireless services including wireless local area (WLAN 2.5 or 5.6 GHz), GSM (1.71-1.88 GHz), PCS (1.93-1.99 GHz), Multiband GNNs, UWB (3.1-10.6 GHz), and for see through wall and concrete application.
