Abstract
A broadband antenna can include a parabolic dish having a diameter D and a radius of curvature that establishes a focal point for the parabolic dish. A tapered slot feed having a feed point can be positioned above the parabolic dish so that its effective radiation point is spaced a distance F from the center of the dish, where F is the focal length of the dish. With this configuration, feed point for the tapered slot feed can be coincident with parabolic dish focal point. The tapered slot feed can include two elements that form an exponentially tapered slot, which establishes a phase center for the tapered slot feed. A conductive bar can interconnect the two elements, in order to minimize the phase center variation during broadband operation.
