Abstract:
A phased array antenna includes an antenna housing including a subarray assembly and a plurality of beam forming modules positioned on the subarea assembly. An antenna support and interconnect member are mounted on the antenna housing and include a carrier member having a front antenna mounting surface substantially orthogonal to the module support for supporting at least one antenna element. A rear surface has a receiving slot. At least one conductive via is associated with the receiving slot and positioned to extend through the carrier member to a circuit element, such as an antenna element, supported by the mounting surface. A launcher member is fitted into the receiving slot and has a module connecting end that extends rearward to a beam forming network.
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.
