Patent ID: 7518565

Claim:
An apparatus, comprising: a cylindrical base; a plurality of tapered slot antennas arranged in pairs; each of said tapered slot antenna pairs further including two antennas having curvatures represented by the equation Y(x)=a(e bx −1), wherein, a and b are parameters selected to produce a desired curvature, x is the length of the antenna and Y is the width of the antenna; each of said tapered slot antenna pairs operatively coupled to said cylindrical base, comprising at least two tapered slot antenna pairs, wherein each tapered slot antenna pair of said at least two tapered slot antenna pairs is selectively operated independently of said other tapered slot antenna pair of said at least two tapered slot antenna pairs to enable direction finding, acquisition, communication and information operations capabilities; and, each said tapered slot antenna pair including two antenna elements, each said antenna element having a feed end and a launch end, said feed end contacting said base so that said antenna element extends radially outward from said cylindrical base.
