Title:
PHASED ARRAY ANTENNA HAVING STACKED PATCH ANTENNA ELEMENT WITH SINGLE MILLIMETER WAVELENGTH FEED AND MICROSTRIP QUADRATURE-TO-CIRCULAR POLARIZATION CIRCUIT
Document Type and Number:
WIPO Patent Application WO2002007332
Kind Code:
A3
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.
