The design of a novel structured monopole super wideband antenna suitable for 5G and 6G mm-Wave and spectrum sensing applications is presented in this work. The proposed antenna features a vast impedance bandwidth in SHF, ranging from 1.5 GHz to frequencies exceeding 40 GHz. The design is implemented using the Ansys Electronics Desktop HFSS tool and constructed on an FR4 substrate with a thickness of 1.6 mm. The design incorporates a modified ground plane combined with a clover-shaped radiating patch. Parametric studies have been conducted to optimize the antenna parameters for achieving the best wideband performance. The proposed antenna radiation characteristics were analyzed using simulations, and the measured results further validate the antenna design.
