在世界范围内，中风是成人残疾的主要原因。中风发生时，血液供应在大脑的一部分是扰乱作为一个血管爆裂或被阻塞的凝块。延迟或错误的医学分析可能对中风患者造成致命影响。本文提出了一种用于脑卒中检测系统的小型天线。该天线提供77%的分数带宽（中心在2 GHz），具有稳定的增益和高的前后比。一个紧凑的雷达为基础的系统开发使用建议的天线中风检测。为了测试该系统，构建了一个出血性中风影响的人头部，模拟人体组织的实际电特性。由后处理算法接收的图像明确地检测并定位笔划的位置。
Worldwide, stroke is the leading cause of adult disability. Stroke occurs when the blood supply in a part of brain is disturbed as a blood vessel bursts or is blocked by a clot. Delayed or wrong medical analysis can be fatal for the stroke affected patient. In this paper, a compact antenna is proposed for the brain stroke detection system. The antenna provides 77% fractional bandwidth (centered at 2 GHz) with stable gain and high front to back ratio. A compact radar-based system is developed using the proposed antenna for stroke detection. To test the system, a hemorrhagic stroke-affected human head is constructed emulating the actual electrical properties of human tissues. The image received by the post-processing algorithm explicitly detects and locates the position of the stroke.
