Abstract
A array of fixably interconnected planar elements equally spaced and orthogonally oriented, that is ultra wide band with a low operating frequency, exhibits steerability in both azimuth and elevation and is capable of dual polarization. The configuration of the array, having a 1:2 ratio of elements to feed lines, allows the implementation of two oppositely driven 50 ohm coaxial feed lines to feed into a single 94 ohm element without the need for custom components or impedance transformers.
