Compact UWB tapered-CPW-fed planar monopole antenna

A planar tapered-CPW-fed monopole antenna, consisting of a circular patch and a trapeziform ground plane, is introduced. Both circular patch and ground plane are printed on the same side of a thin substrate, therefore the antenna can be easily fabricated with low cost, and achieve an extremely wide impedance bandwidth because of the tapered CPW feeder and… (More)
