This paper reveals Koch Like Sided Sierpinski Square Carpet Multifractal Antenna (KLSSSCMA) having wideband features and comprises a new hybrid geometry using Sierpinski carpet and Koch curve geometries. The antenna is designed using square patch having dimensions 29.4 mm × 29.4 mm over Roger RT/Duroid substrate having height equal to 3.18 mm and dimensions 48.48 mm × 48.48 mm. The proposed antenna is analyzed and simulated using FEM (Finite Element Method) based Ansoft HFSSTM v.13 software successfully up to fourth iteration. Simulation results show that KLSSSCMA has wideband characteristics from 2 to 8 GHz that covers S and C bands for WiMAX, WPAN, WLAN and Wi-Fi applications. The projected antenna is capable of achieving a good impedance bandwidth with S11 less than -9 dB over the whole range of BW and also exhibits almost stable radiation patterns.
