“…The evaluation of the antenna from the previous works with the proposed antenna is presented in Table 6. Considering the antenna with compact size, only antennae from [13][14][15] and [16][17][18] are being considered for the evaluation. One of the main requirements for head imaging is the antenna must operate within the range of 1 GHz to 4 GHz; thus, the antennas that are capable of operating within the ranges are from [13], [17] and [18].…”

“…Thus, this antenna does not meet the recommended criteria for head imaging and will later affect the resolution of image reconstruction. A defected ground structure (DGS) based ultrawideband (UWB) monopole is presented in [16]. In this research, a spherical shape model mimicking the human head inserted with a tumour is used to be tested with the presented antenna.…”

The development of antipodal Vivaldi antenna with a fractal slot is presented in this paper due to its promising application as an element of possible multisensory systems of head stroke imaging. The fractal slot is applied to improve the directivity, bandwidth and gain of the antenna. Hence, this research mainly aims to create and optimise a compact Vivaldi antenna through the fractal slot for the detection of stroke in the human head. The antenna is designed with an overall dimension of 65 × 65 × 1.6 mm 3 using Roger RO4350B as a substrate through the CST Studio Suite 2019 software. The proposed antenna will also be compared with an antipodal Vivaldi antenna without the fractal slot to observe differences in the result. The proposed antenna can produce a wide bandwidth of 1.44 GHz ranging from 2.35 GHz to 3.79 GHz at the maximum gain of 7.35 dBi. Furthermore, the prototype antenna has a directivity characteristic, which produces the unidirectional radiation necessary for microwave imaging procedures. The proposed antenna is also evaluated with the CST studio head model, thus providing satisfactory penetration results through the head tissue. A value of 0.0013 W/kg per 10 g is achieved for the maximum SAR. Thus, the proposed antenna met most of the requirements for the imaging process, which will affect its effectiveness during scanning of head stroke.
