Worldwide, stroke is the leading cause of adult disability, the brain stroke is the third cause of death, ranking only behind heart disease and cancers. 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. It also causes serious long-term disabilities which lead significant economic impact. Therefore, the real-time diagnosis is important, in this paper a UWB Pentagon antenna is designed to detect brain stroke and brain tumor. The use of UWB (Ultra-Wide Band) in stroke detection opens the possibility to develop low cost, fast response and transportable diagnostic devices, which could play a key role in emergency scenarios. It is operating at a band from 3.3568-12.604 GHz in free space and from 3.818 to 9.16 GHz on the normal head model. The antenna has dimensions of 44x30mm2. It is fabricated on FR4-substrate with relative permittivity 4.4 and thickness 1.5mm. The antenna is simulated on the HFSS software and measured using the network analyzer. There is a good agreement between the measured and simulated results of the return loss of the antenna on human’s head and head phantom.
