A novel antipodal Vivaldi antenna (AVA) is proposed in this letter. The addition of regular slot edges (RSE) helps the antenna lower the low-end operating frequency by 9% with the dimension unaltered, while the radiation patterns at higher frequencies are improved due to the loaded lens and the choke slot edges (CSE) configuration at the termination of the flares, which also contribute to the enhancement of antenna gain. The improved antenna is fabricated and verified experimentally. The measured results coincide with the simulated ones perfectly, which proves the feasibility of the novel design.
