“…Having a narrow Band width from microstrip patch was difficult at the beginning, therefore, the researchers in [8] relay on dipoles and distributed slots antenna design. Accordingly, many researchers found that best way to improve the omni directional by increasing the matching The Scientific Journal of Cihan University -Sulaimaniya impedance characteristics bandwidth ratio, therefore it was important to maximize the overall size of antenna feeder and height as in [9].…”

“…An ultra-wideband (UWB) antenna is suitable for the capability of penetration at various depths. Accordingly, UWB antennas have recently received a large concentration to propose developed systems with efficacious antennas [1][2][3][4][5][6][7][8][9][10][11][12]. In this context, different GPR antennas have been presented in recent literature, such as those presented in [13][14][15][16][17][18][19][20][21][22].…”

A printed U-shaped coplanar waveguide fed (CPW) ultra-wideband (UWB) antenna is designed, fabricated, and measured in this paper for ground penetrating (GPR) applications. To enhance the working bandwidth, a set of cutoffs was introduced in different parts of the antenna. The antenna was printed on the FR4-epoxy substrate in a compact size of 0.252λ0×0.3λ0×0.015λ0 at 3 GHz. The calculated results were validated by realizing and measuring a prototype. Experimental demonstrations were done with the R& S®ZNB Vector Network Analyzer, which indicates that the antenna's working bandwidth extends from 3.09 GHz to 11.07 GHz (112.71%). Additionally, the antenna's radiation patterns were measured in an isolated anechoic chamber, which shows that the proposed antenna has omni-directional radiation patterns. Moreover, acceptable gain antenna values ranging between 1.74 and 7.04 dBi and high values of radiation efficiency of more than 80% were achieved over the whole working bandwidth. Besides, the antenna presents a stable group delay with a linear phase of S21 through the UWB frequency band. To prove the efficiency of the fabricated antenna for GPR applications, the operation of the antenna was experimentally tested in a sandy soil box. The obtained results show that the proposed antenna could be a good candidate for GPR applications.
