A broadband millimeter-wave phased array system is presented which allows for independent control of vertically and horizontally polarized beams in azimuth and elevation. The complete system is based upon low profile tray architecture with compact spacing between adjacent elements and ease of integration with multiple linear arrays. Using stereolithography, a dual polarized waveguide structure was fabricated which allowed for a low loss transition between an array of miniature horn antennas and the array ports of the phase shifting network. A broadband switch network with low noise amplifier was designed to achieve a compact electronically controlled phased array.
