  • Tapered slot antenna cylindrical array
    Patent number: 7679575
    Abstract: A Tapered Slot Antenna Cylindrical Array (NC#98219). The method includes coupling at least two tapered slot antenna pairs to a base element in a cylindrical configuration. The method may further include coupling a transmitter/receiver to each tapered slot antenna of the at least two tapered slot antenna pairs via radio frequency links. In addition, the method may further include coupling a microprocessor to the transmitter/receiver via communication links.

  • Tapered slot antenna cylindrical array
    Patent number: 7518565
    Abstract: A Tapered Slot Antenna Cylindrical Array (NC#97194). The apparatus includes a base and a tapered slot antenna array. The base is capable of retaining a plurality of tapered slot antenna pairs. The tapered slot antenna array is operatively coupled to the base in a cylindrical configuration. The tapered slot antenna array comprises at least two tapered slot antenna pairs. Each tapered slot antenna pair of the at least two tapered slot antenna pairs is capable of operating independently of or in conjunction with other tapered slot antenna pairs of the at least two tapered slot antenna pairs to enable direction finding, acquisition, communication and electronic attack capabilities.

  • Tapered slot antenna
    Patent number: 7009572
    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.
