Abstract :
A tapered slot Vivaldi antenna, which is fed by a microstrip-slot balun for 1-8GHz Wideband application is presented. The measured bandwidth of the proposed antenna for |S11| ≤-10 dB spans 0.9GHz to 9.6 GHz. The endfire radiation patterns in the x-y and y-z plane are obtained through the operating band from 0.9GHz to 5.8GHz. The antenna peak gain is 6.3 dB and measured gain is larger than 3.15 dB from 0.9GHz to 6GHz, however, the gain has a sharp decline at 8GHz. The structure and parameters of the Vivaldi antenna is designed and simulated.
