Abstract

A conventional antipodal Vivaldi antenna has characteristics of multiple-octave operation bandwidth but also relatively low directivity, main beam offset direction and asymmetric radiation patterns with frequency variation. In order to improve the directivity and radiation patterns, a design of a double-slot antipodal Vivaldi antenna is proposed. It makes synthetic radiation patterns by complementary patterns of the double-slot structure. As a result, it has center-directional and symmetric radiation patterns. The proposed antenna has an operating frequency range of 2-18 GHz. Directivity of the proposed antenna is improved at high frequencies as compared the conventional antipodal Vivaldi antenna.
