Abstract
A phased array antenna includes an antenna housing having a subarray assembly that supports beam forming network modules and an array face defining a ground plane substantially orthogonal to the subarray assembly. A plurality of millimeter wavelength patch antenna elements are positioned on the array face and each positioned adjacent a respective subarray assembly. The millimeter wavelength patch antenna elements each include a driven antenna element having a front and rear side and a parasitic antenna element positioned forward of the front side of the driven antenna element. A microstrip quadrature-to-circular polarization circuit is positioned rearward of the rear side of the driven antenna element and operatively connected to the driven antenna element. A single millimeter wavelength feed operatively connects the microstrip quadrature-to-circular polarization circuit with a respective adjacent beam forming network module supported on the orthogonal positioned subarray assembly.
