Abstract: The invention relates to a dual polarized wideband array antenna using orthogonal feeding technique to have a low profile and a cosecant squared beam. The array antenna includes three main parts: the element antennas, the orthogonal feeding structure and the feeding network. The spatially orthogonal feeding structure is a transition between the microstrip lines on element antennas and the striplines on the feeding network. The top layer of the feeding network operates as a ground plane for the array antenna. Due to the disparities between the stripline lengths, the phase parameters of element antennas are optimized to create a cosecant squared radiation pattern.

Abstract: A parameterized geometric model of a structure can be determined based on spectra from a wafer metrology tool. The structure can have geometry-induced anisotropic effects. Dispersion parameters of the structure can be determined from the parameterized geometric model.
