We propose a novel direction-of-arrival estimation technique for ultra-wideband (UWB) electromagnetic waves, which allows for the effect of the antenna mutual coupling. This technique is comprised of a UWB interferometry, a multiple signal classification (MUSIC), and a database. The effectiveness of our scheme is demonstrated through numerical examples.

The narrow bandwidth at low frequency of current available wireless capsule endoscopy do not provide clear images of digestive organs. The Ultra Wideband (UWB) at frequency of 3.1-10.6 GHz is one of the possible frequency band to provide clear images from small intestine and stomach. This paper discusses on an UWB antenna to be placed inside stomach of a human body model.

Lens antennas, which can transform the incident spherical wavefronts to planar above radiating aperture, have attracted increasing attention due their simple structure and high gain performance. Nevertheless, conventional lens antennas face with problem of dispersion effects, hinders applications in large bandwidth multi-channel communications. In this article, we propose a millimeterwave achro...

Detect breast cancer in early stages, ensure a comfortable and cheap diagnostics in order to reduce women mortality, are the challenges of this paper. A compact ultra wideband (UWB) Planar antenna for Microwave thermography system is designed and simulated using two commercial software, CST Microwave Studio and HFSS simulators.
