A novel antenna array for stroke enhanced detection

A novel antenna array for stroke enhanced detection is presented in this paper. The array consists of two new designed UWB antennas and two half-wave E-dipole, placed symmetrically around a 3D head model with equally distances to the origin. The head model is Cole-Cole parameter based and made by six dispersive spherical layers, representing different tissues of the head. An approach to determine the locations of E-dipole are also given. Our achieved simulation shows that the array is validated in 0.75-1.2 GHz with enhanced detecting sensitivity from several testing cases involving different stroke sizes and locations. It makes the array is potential for brain stroke detection.
