Abstract:
A simple compact printed slot antenna fed bycoplanar waveguide (CPW) with a pair of parasitic patches thatare added in back side of antenna is presented. By embeddingan H-shaped strip to the feed line and symmetrical inverted L-shaped strips that are connected to the H-shaped strip, theimpedance matching has improved and the bandwidth (BW) isextremely enhanced. The total size of the antenna is25×25×1mm3 and operates over the frequency range of 3-15. 5GHz. For the fabricated antenna, omni-directional patternis observed over the whole UWB frequency range.
