Abstract
A planar UWB slot-antenna with a size of 35×35mm2 is proposed for stroke detection. The antenna is optimized for operation directly on human skin in the frequency range from 1 to 9 GHz. A sector-like slot is applied to the design to enhance the bandwidth regarding the current distribution. The near-field performance of the antenna is characterized and verified by the measurements. Benefiting from a symmetrical structure and differential feeding technique the antenna owns a very stable radiation behavior in the whole frequency range and a very high front-to-back ratio which would improve the stroke detection capability of the brain imaging system with robust performance.
