A Novel Design of Directive Ultra Wide Band (UWB) Triangular Sheet Antenna

In this paper, a new design for an Ultra Wide Band (UWB) antenna is proposed. The frequency domain analysis of the projected antenna has been probed to show its capability as an operative element to be used for UWB purposes. The return loss (S
₁₁
) is less than-10 dB along the operational bandwidth of 3 GHz to 20 GHz (147% fractional bandwidth). In this paper, The simulated return loss, input impedance and radiation pattern are presented and it has been shown that proposed antenna is very useful for impulse and UWB communication systems (in radar communication, for military application, bio-medical technology, space communication through satellite etc.). As the proposed antenna has an end fire radiation pattern it is very useful in point to point communication with very high gain performance.
