TL;DR: In this article, an ultra-wideband (UWB) U type monopole antenna fed by a coplanar waveguide (CPW) is proposed, which has low profile and very compact size (14.48 mm × 28.74 mm × 0.8 mm).
Abstract: An ultra-wideband (UWB) U type monopole antenna fed by a coplanar waveguide (CPW) is proposed. It has low profile and very compact size (14.48 mm × 28.74 mm × 0.8 mm). It provides an wide impedance bandwidth ranging from 3.08 GHz to about 12.75 GHz adjustable by variation of its parameters, such as the relative permittivity and thickness of the substrate, width, and feed and ground plane dimensions. Parametric study is presented. Details of the proposed ultra-wideband design are described. Simulation results are presented and discussed in this paper.

TL;DR: In this article, the authors introduce a smart NDI tool using active W-band imaging, which is capable of detecting hidden surface cracks in concrete structures. But this tool is not suitable for non-collapse detection.
Abstract: This paper overviews the latest trends of millimeter- wave (MMW) imaging technologies, focusing mainly on applications of and technical parameter variations for security surveillance and nondestructive inspections (NDI). We introduce a smart NDI tool using active W-band imaging, which is capable of detecting hidden surface cracks in concrete structures.

TL;DR: In this paper, a new circular ultra-wideband fractal monopole antenna based on descartes circle theorem (DCT) with elliptical iterations is presented, which is optimized for return loss below −15 dB.
Abstract: A new circular ultra-wideband fractal monopole antenna based on descartes circle theorem (DCT) with elliptical iterations is presented. The proposed fractal design is optimized for return loss below −15 dB. The basic structure is slightly modified to ensure an overall smooth current distribution limited by the junction point nature of the fractal geometries. The measured return loss of the proposed design is below −15 dB within its impedance bandwidth along with omni-directional radiation pattern. Moreover due to the fractal shape, the proposed design has less weight and wind loading effect.

TL;DR: Anovel ultra-wideband bow-tie slot antenna fed by CPW is proposed in this paper, which has been demonstrated to provide an UWB with return loss less than −10 dB from 9.5 GHz to 22.4 GHz.
Abstract: Anovel ultra-wideband bow-tie slot antenna fed by CPW is proposed in this paper. This antenna has been demonstrated to provide an UWB with return loss less than −10 dB from 9.5 GHz to 22.4 GHz. The bandwidth is up to 80%, which is quite better than the traditional bow-tie slot antenna. Simulated and measured results are presented.
