Abstract

A Novel Miniaturized Vivaldi Antenna utilizing resonant structure to extend the low-end bandwidth limitation is presented in this paper. The low-end bandwidth limitation of the proposed antenna has extended to 2.45 GHz from the original 3.07 GHz. In addition, the gain of the proposed modified antenna has a significantly improvement compared with the conventional Vivaldi antenna at the same size, the directivity has been improved too in the lower frequency. Moreover, the group delay of the antenna shows that the proposed antenna has a good time-domain response.
