In this paper, shaped printed Microstrip Patch Antenna (MPA) for a remote sensing application that operates in the ultra-wide band (UWB) spectrum is reported. By converting the upper side of a traditional rectangular patch into a semi-circular shape and the lower side into a shape like a staircase, the suggested radiating patch is created. Physical and electrical volume of the presented antenna is 33 x 24 x 1.6 mm3 and 0.253 λ0 x 0.184λ0 x 0.012λ0 respectively. The proposed antenna is developed, optimized, and simulated with Computer Simulation Technology's (CST) Microwave Studio Suite software. The antenna is developed on a 1.6 mm-thick FR4 dielectric substrate, featuring a loss tangent of 0.09, relative permittivity of 4.4 and measured using standard microwave test bench. Measured outcome of the suggested antenna confirms a wide impedance bandwidth of 13.7 GHz (2.3-16 GHz) with a fractional bandwidth of 149.7 % and Bandwidth Dimension Ratio (BDR) of 3215. Within this frequency range, the proposed antenna exhibits a peak gain of 3.9 dBi. Additionally, adequate co-polarization and cross-polarization separation are attained in all directions for the proposed antenna. The designed antenna is compact and lightweight, exhibits consistent gain, and is compatible with wireless system equipment. The UWB antenna may be used with Surface Penetrating Radar to detect explosive and dangerous things underground.
