The objective of this work is to design and optimize an Ultrawideband planar rectangular printed antenna with band notched behavior intended to get rid of the 5-6 GHz frequency band for WLAN compatibility purposes. The antenna has a large bandwidth covering the frequency band from 3.1 to 10.6 GHz, and the radiation patterns are similar to those of a conventional dipole antenna. In order to improve...
A method is described to reject certain bands within the passband of an ultrawideband (UWB) planar antenna using parasitic elements. In the presented design, the antenna is created by a planar monopole and a ground plane both of half circle shape, whereas parasitic elements are in the form of printed strips. Four examples of UWB antenna design are shown. The first design is without parasitic, while...
