Reem ; Assalem, Dr. Abdulkarim 	Brain Cancer Detection Using U-Shaped Slot VIVALDI Antenna and Confocal Radar Based Microwave Imaging Algorithm	2020	13	.pdf	application/pdf	3590	170	57	As it is shown in Fig.5, values of Gain of conventional VIVALDI antenna are between [2.97-6.62] dB while values of Gain of U-shaped slot VIVALDI antenna are between [4.22-7.36] dB so that U-shaped slot VIVALDI antenna increases values of gain through frequency band and it is more stable than conventional antenna over the bandpass.
