This paper describes a novel Super-Wideband monopole antenna for THz applications. It has a Super-Wideband performance (3-16 THz) and up, which presents a fractional bandwidth greater than 135%. It has 2:1 VSWR with 10 dBi peak realized gain and flat group delay. These results satisfy the frequency and time-domain characteristics of the antenna. The radiator and ground plan of the antenna are based on quadratic Bezier outlines, which can be optimized with few control points. The proposed antenna is designed on Rogers RT5880 substrate (εr = 2.2) with a very compact size (42 × 32 × 1.6 μm³). Therefore, this antenna can be used in THz wireless communication systems such as T-WPAN, T-WBAN, and T-WLAN. It can be employed as an elementary antenna on MIMO systems
