Abstract

A simple compact printed slot antenna fed by coplanar waveguide (CPW) with a pair of parasitic patches that are added in back side of antenna is presented. By embedding an H-shaped strip to the feed line and symmetrical inverted L-shaped strips that are connected to the H-shaped strip, the impedance matching has improved and the bandwidth (BW) is extremely enhanced. The total size of the antenna is 25×25×1mm³ and operates over the frequency range of 3-15.5GHz. For the fabricated antenna, omni-directional pattern is observed over the whole UWB frequency range.
