“…At high frequencies around 9.5 GHz, the measured radiation pattern in the E-plane is no longer bidirectional. The small deformation at higher frequencies is probably due to the excitation of higherorder modes [18][19]. Figure 7 depicts the measured and 02 dBi attained at about the frequency of 5.15 GHz.…”

In this paper, a coplanar waveguide (CPW) fed slot antenna using fractal-shaped isosceles trapezoidal corrugations is designed and presented for Ultra-Wideband (UWB) applications. The proposed antenna is formed by a regular hexagonal patch fed through a CPW feed line and radiates amidst a notched wide hexagonal slot. The edge of the wide slot is shaped by a fractal structure that is formed by five trapezoidal notches. The antenna is printed on RO4350B substrate having a compact size of 0.305λ0 × 0.313λ0 × 0.012λ0 at 2.35 GHz. . Good agreement is registered between the experimental results of the fabricated prototype and the calculated ones. By using an Agilent 8722ES vector network analyzer, the fabricated prototype confirms that the antenna has an excellent matching impedance over the bandwidth 2.35-10.65 GHz (127%) which covers the entire UWB band. Furthermore, good radiation performances are measured in an anechoic chamber. Consistent radiation patterns with a reasonable peak gain are measured over the entire working bandwidth. Therefore, the designed structure may be worthily considered for different wireless communications systems.

“…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.

The article presents the results of research on the physical and radiological properties of building ceramics made of mining waste. One method of using mining waste is to use it as aggregate in road construction. However, this alone is not enough to dispose of the entire amount of waste generated. Another promising method of using mining waste is the production of building ceramics (bricks). However, some properties (e.g. the content of natural radionuclides) of the waste may limit the possibility of such use. In the scope of this work, the properties of bricks made from mining waste - shale collected from dumps, were examined. It has been shown that the properties of bricks prepared in this way meet the criteria set out in various standards and legal acts and can be used in construction.
