An UWB Tapered Slot Vivaldi Antenna (TSA) with Improved Characterestics
In this paper, an UWB Tapered Slot Vivaldi Antenna (TSA) is presented. The proposed TSA is optimized in order to increase the bandwidth and ensure a good impedance matching at low and bandwidth frequencies while respecting the low profile. The overall size of simulated antenna is $45\times 40\times 0.8\ \text{mm}^{3}$. This antenna is designed in order to be used in bio medical application and some other radar based microwave imaging.
