ABSTRACT:
An improved tapered slot antenna. The structure includes a first antenna element, a second antenna element, a brace, a semi-infinite balun and a radome. The first and second antenna elements are operatively coupled to the brace in a tapered slot antenna configuration. The first and second input feed of the semi-infinite balun are operatively coupled to the first and second antenna elements, respectively, so that the second input feed is situated along substantially an entire length of a feed channel of the second antenna element. The radome is operatively coupled to the first and second antenna elements. A method for fabricating improved tapered slot antennas is also described.
