Description
Summary:In this paper, a combined tomographic imaging system comprising the rotation of a multiplexed linear antenna array around the object under test is designed. With this system a cylindrical sampling is obtained, allowing to scan realistic phantoms without important restrictions on its shape. This, combined with the non-application specific 3D ultrawide band (UWB) Hybrid Focusing reconstruction algorithm, allows to use this system in a wide range of applications. The design of a multiplexed array of UWB antennas for medical applications entails significant challenges including a large impedance bandwidth, small size and low coupling between elements, which will be treated in this paper.
