Design a new notched UWB antenna to rejected unwonted band for wireless communication

C-shape resonant
Notched UWB unwonted band
Rectangular band-notched
Ultra-wideband antenna

This paper presents a slotted design for ultra-wideband (UWB) antenna.
Design of a rectangular UWB antenna covering the frequency range 3.1-10.6
GHz, to achieve notch characteristics in the bands at 3.1-8.4 GHz and 8.6-
10.6 GHz. By changing the direction of distribution of current to apply this
technique by inserting three C-shaped holes and two pairs of rectangular
notches below the antenna. The simulation results reveal that the proposed
structure is in good accord with the simulation results. The proposed UWB
antenna size is (100x90x1.6 mm)3

. This proposed design could provide a
solution to eliminating bands that interfere in a UWB band depending on the
aperture design. The simulated findings reveal that the UWB antenna
operates in the 8.5 GHz center frequency range and rejects all frequency
bands utilizing slits. This antenna design can provide a solution to remove
UWB bands from 3.1-10.6 except for 8.5 GHz which only works. By using
the notch, we got a large increase in the gain. makes to be a suitable
candidate for X-band-UWB applications.
