“…Compact antennas exhibiting ultra-wide bandwidth is considerably possessing low gain and omni-directional radiation pattern which is commonly used for short distance and low resolution [4]. This type of antenna could be used in the Ground-Penetrating Radar (GPR) application also [16][17][18][19][20][21]. While on the other hand, use of UWB antennas for detection purpose in microwave imaging systems, requires somewhat better gain and radiation pattern.…”

-In this work, an ultra-wide band (UWB) microstrip antenna is designed which can be used for microwave imaging applications such as breast cancer detection. Proposed antenna is operating in between 2.01GHz to 7.64GHz with a Fractional Bandwidth (FBW) of 116%. Antenna is using low cost low profile substrate with 38 × 40mm 2 dimensions and thickness of 1.6mm. This antenna can provide maximum gain of 9.4dB, which is considerably a good result for microwave imaging purpose.

An ultrawide bandwidth (UWB) antenna for ground-penetrating radar (GPR) applications is designed to check soil moisture and provide good-quality images of metallic targets hidden in the soil. GPR is a promising technology for detecting and identifying buried objects, such as landmines, and investigating soil in terms of moisture content and contamination. A paddle-shaped microstrip antenna is created by cutting a rectangular patch at one of its diametrical edges fed by the coplanar waveguide technique. The antenna is loaded by stubs, shorting pins, and a split-ring resonator (SRR) metamaterial structure to increase the antenna’s gain and enhance the bandwidth (BW) towards both the lower and higher end of the working BW. The antenna’s performance in soil inspection is studied in terms of the operating frequency range, different types of soil, different distances (e.g., 50 cm) between the antenna arrays and soil, S-parameters, and gain. Following this, the antenna’s ability to find a metallic target in the soil is tested, considering different array numbers, multi-targets, and locations. The antenna is designed on a thin layer of economic polytetrafluoroethylene (PTFE) substrate with dimensions 50 × 39 × 0.508 mm3 and works in the frequency range 1.9–9.2 GHz. In addition, two more resonances at 0.9 and 1.8 GHz are also achieved; hence, the antenna works for more than two application bands, such as the ISM- and L-bands. The measurement results validated excellent agreement with the simulated results. Furthermore, the recommended antenna offering a high gain of about 10.8 dBi and maximum efficiency above 97% proved able to discriminate between hidden objects and even recognize their shapes. Moreover, the reconstructed images show that the antenna can detect an object in the soil at any location.
