Abstract: This paper presents a review work on printed monopole antenna. Different shapes of patch and ground plane to achieve ultra wide band (UWB), have been surveyed and summarized in this paper. Step rectangular, circular, octagon, U-shaped and step circular patches are used to achieve maximum impedance bandwidth ratio of around 15:1. On other side notched, saw tooth and rounded ground plane provides a maximum impedance bandwidth ratio of around 5.5:1. Trapeziform ground plane with a discone antenna provides maximum impedance bandwidth ratio of 23:1.
Keywords: Printed monopole antenna, Ultra wide band, impedance bandwidth ratio.
