A super-wideband (SWB) steering-shaped printed monopole antenna (SPMA) having a ratio bandwidth (RBW) close to 11:1 is presented in this paper. Partial ground plane with rounded top corner and a rectangular notch are used to get wide bandwidth. Good impedance matching is achieved by a microstrip feed line with linear tapering. A 22.78 GHz bandwidth for S11 ≤ −10 dB is achieved from 2.22 GHz to 25 GHz. A 4 dB average peak gain and a variation from 96% to 57% in radiation efficiency are observed. The simulated far-field patterns in the two principal planes at different frequencies are presented. The proposed radiator can be used for different civilian and military applications.
