Abstract :
A brain imaging system that uses a circular array tapered slot wideband antennas is reported. The antenna utilized in the array is a corrugated microstrip-fed tapered slot antenna of compact dimensions (24 mm × 24 mm) immersed in a suitable coupling liquid for improved matching with the brain tissues. To protect the antenna elements from the harmful effects of the coupling liquid a dielectric sheets are used to cover the radiating elements. The proposed circular array includes ten wideband antenna elements that are designed to operate efficiently across the band from 1 GHz to 4 GHz. The developed array is tested using a phantom that emulates a stroke affected brain.
